Donald Trump has a message for celebrities who say they'll leave the country if he's elected president: Pack your bags.

The Republican presidential front-runner said Tuesday on 'Fox & Friends' that purging the United States of Rosie O'Donnell, Whoopi Goldberg and Lena Dunham would be a pot sweetener if he wins the White House.

'We'll get rid of Rosie? Oh, I love it. Now I have to get elected!' he said during an early morning phone-in interview.

'Now I have to get elected because I'll be doing a great service to our country. I have to. Now it's much more important. In fact I'll immediately get off this call and start campaigning right now.'

GOOD RIDDANCE? Trump has publicly feuded with Rosie O'Donnell (left) and Whoopi Goldberg (right), making their departure seem like more of a feature than a bug

Trump's glee at the idea of an America free of Rosie O'Donnell stems from years of public feuds with the actress.

He also jumped for joy on Fox News at Goldberg's threat that 'maybe it's time for me to move' if he wins in November.

'That would be a great, great thing for our country if she did that,' Trump jabbed.

Asked about Lena Dunham, who pledged Monday to move to Canada for the duration of a Trump presidency, the billionaire scoffed.

'She's a B actor, and has no – you know – mojo,' he said.

Dunham said Monday at the Matrix Awards that 'I know a lot of people have been threatening to do this, but I really will.'

'I know a lovely place in Vancouver and I can get my work done from there.'

The star of HBO's 'Girls' show has been a vocal Hillary Clinton supporter, campaigning with the Democratic front-runner on several occasions.

'GIRLS,' INTERRUPTED? Lena Dunham is the latest entertainer to pledge that she'll fle the country if Trump wins the White House

Goldberg said in January on 'The View' that 'I can afford to go.'

She hinted that she believes Trump's focus on illegal immigration has parallels with Nazi Germany.

'I've always been an American, and this has always been my country and we've always been able to have discussions. And suddenly now it's turning into, you know – not them, not them,' she said.

'And you know, we have a lot of friends whose parents saw this already. They don't want to relive this ... So I need all the candidates to get it together. Get back to American values.'

Another 'View' co-host, 30-year-old Raven Symone, boasted in February that she already had her escape route to Canada planned if the presidential election doesn't end the way she wants it to.

'My confession for this election is if any Republican gets nominated, I’m gonna move to Canada with my entire family,' she said in February.

PACK YOUR BAGS: Raven Symone, Cher and Al Sharpton have all said they'll make tracks and leave the United States rather than endure four years under a President Trump

Since a Republican is nominated for president every four years, Symone's promise is an iron-clad pledge to emigrate.

'I already have my ticket. I literally bought my ticket, I swear,' she insisted.

Donald Trump Jr., the real estate titan's son, said in late February that he would fund the exit of any famous people who want to abandon the country in a Trump administration.

'I'll buy them their airfare,' said Donald Jr. 'Those are endorsements for Trump.'

The candidate later said he would 'join with my boys and bank for it.'

Cape Breton, in the furthest reaches of Nova Scotia, Canada, has seen interest in tourism spike along with celebrity talk of fleeing America next year.

A website called 'Cape Breton if Trump Wins' now talks up the island as a diversity-friendly place with 'the most affordable housing market in North America.'

Rob Calabrese, a Canadian radio host, launched the effort this winter.

Cher, Eddie Griffin, Barry Diller, Al Sharpton, Jon Stewart, Samuel L. Jackson and Omari Hardwick have all publicly discussed moving outside the U.S. if Trump wins.

NOT FUNNY: Comics Eddie Griffin and Jon Stewart, along with Samuel L. Jackson, say they'll jump off the Trump Train and make a run for the border

DailyMail.com columnist Katie Hopkins, who appeared in the 2007 season of 'The Apprentice,' says she'll move too – to the United States.

Trump spoke early in the morning on Fox before polls opened in five Northeastern states: Connecticut, Delaware, Maryland, Pennsylvania and Rhode Island.

All told, there are 172 Republican National Convention delegates up for grabs, and Trump is expected to win the lion's share.

The billionaire real estate developer is on track either to narrowly capture the GOP presidential nomination, or to fall short by a razor-thin margin.

Tuesday morning he crested the 50 per cent level in an NBC News / SurveyMonkey poll of Republican primary voters for the first time, a sign that his populist appeal is gaining him new converts.

After Tuesday, however, the race moves westward.

Texas Sen. Ted Cruz and Ohio Gov. John Kasich have both abandoned the Northeast. Cruz is campaigning furiously in Indiana while Kasich has his eyes on Oregon and New Mexico.

Both men aim to spend time where their candidacies are strongest in a bid to deprive Trump of every delegate that can be pried away from him.

A deal struck between the two seasoned politician on Sunday night called for Cruz to stay out of Oregon and New Mexico, and Kasich out of Indiana, in order to limit the extent to which they will 'split' the anti-Trump vote.

The New York tycoon called the bargain a form of desperate 'collusion,' and mocked Kasich Monday in Pennsylvania after he told reporters that he hoped Indianans would vote for him anyway.

The first Republican contender to win the support of 1,237 delegates – the barest majority possible – will be the party's nominee. Trump hopes to accomplish that on June 7 when the dust settles after the California primary.

But Cruz and Kasich know their only chance to win lies in stopping Trump short of that magic number, throwing the July convention into Cleveland chaos and turning Trump's 'bound' delegates into free agents who can switch their allegiance.
