Former NBA star Dennis 'The Worm' Rodman arrived in Singapore late Monday night, hours before President Donald Trump is set to meet North Korean dictator Kim Jong-un for the first time.

Rodman emerged from the baggage claim area at Changi airport around midnight and told reporters he wasn't sure if he would meet Kim.

Last week the prolific rebounder, who has traveled to North Korea at least five times, said he would 'give whatever support is needed' to his 'friends' – meaning both Trump and Kim.

White House officials have said Rodman will play no official role in the diplomatic negotiations. Trump said last week that Rodman had not been invited to the summit.

Retired NBA player Dennis Rodman arrived in Singapore just after midnight local time, reaping the publicity associated with being one of few westerners to spend time with KimJong-un; the North Korean despot is meeting with President Donald Trump on Tuesday for nuclear talks

Rodman has been to Pyongyang at least five times, and once sang 'Happy Birthday' to the brutal dictator and presented him with a copy of Trump's book 'The Art of the Deal'

Trump has promised that the U.S. will keep up his 'maximum pressure' campaign against Kim until he completely abandons his nuclear weapons program

He is one of the few westerners to have met the North Korean leader on visits to the capital city Pyongyang.

'Thanks to my loyal sponsors from @potcoin and my team at @Prince_Mrketing, I will be flying to Singapore for the historical Summit,' the former Chicago Bulls forward tweeted late Friday.

PotCoin is a cryptocurrency invented to support the cannabis trade.

Trump told reporters Thursday that he wasn't aware the 6-foot-7 former NBC star would be in the neighborhood for the nuclear disarmament summit.

'Dennis Rodman? No. I didn’t know about Dennis,' he said in the Oval Office.

'He was not invited, but he's a nice guy. I like him,' Trump added.

Rodman has had actual face-time with Kim in the past, but the White House doesn't wnat him underfoot to complicate Tuesday's delicate negotiations

As he left the White House for Canada on Friday morning, the president seemed more interested in praising Rodman's athletic talents than in drafting him into the State Department.

'When you think Dennis was a great rebounder and he wasn't relatively speaking that tall. So that tells you, you know – there's a rebounding, there's a genius for that. Dennis Rodman was a great rebounder,' Trump said.

Deputy Press Secretary Hogan Gidley was less diplomatic, making it clear in a Fox News Channel interview a day earlier that Trump planned to manage just fine without the tattooed and lip-ringed athlete hanging around.

'We have a schedule set of what we’d like to see accomplished, and what we want is denuclearization of the peninsula,' Gidley said on the 'Fox & Friends' program. 'That’s been what the president has been talking about – verifiable, irreversible denuclearization.'

'I don’t know what part the best rebounder in basketball has to play in that.'

The unlikeliest diplomat: Rodman arrived in Singapore wearing a t-shirt advertising PotCoin, a cryptocurrency developed to give legal marijuana dealers a way to store their profits despite not having access to U.S. banks

Kim and Rodman have famously built a bizarre friendship, and the former basketball player brought the crutal despot a copy of 'The Art of the Deal' for his birthday last year.

That trip was also sponsored by PotCoin.

In 2013 the two-time 'Celebrity Apprentice' contestant declared Kim was was his 'friend for life.' That came after three visits to Pyongyang that year, including one organized by the Harlem Globetrotters.

Rodman has previously claimed he was partly responsible for easing the tension between Trump and the Kim regime.

The athlete told TMZ in April that Kim has had 'a change of heart' about his feelings toward Trump and the U.S.

'I don't want to sit here and say, I did this and I did that. That's not my intention,' Rodman said, adding that his intention was to go to the North and be an ambassador.

North Korea's Kim Jong-un and President Donald Trump are gearing up for an unprecedented summit in an attempt to address the last festering legacy of the Cold War, with the US President calling it a 'one time shot' at peace – and Rodman wants a piece of the historic legacy

In March, Rodman tweeted a photoshopped picture of his friend Kim, wearing a 'Make America Great Again' hat.

'Hoping for this after my two friends and leaders meet next month #Peace #Love #NotWar #Diplomacy,' Rodman wrote.

In a December 2017 interview with Stephen Colbert, Rodman offered to work as an envoy to North Korea.

'I'm close enough to him to the fact that he can discuss anything with me,' he said.

'But the deal is, I don't discuss politics because that's not my job. My job is to be a human being, to try and connect us with him.'
