Mayor Pete Buttigieg has picked up one of the most influential Hollywood financiers as a backer, as he continues to surge in the 2020 fundraising battle, his campaign told CNBC.

Nicole Avant, one of President Barack Obama's lead bundlers during his first run for president, has decided she's going all-in to back the South Bend, Indiana, mayor's run for president.

"She's a key supporter who is bundling for us, and hosting an event for us this month," a campaign spokesman told CNBC. The spokesman said tickets for the Avant gathering will go for up to $2,800.

Avant did not return requests for comment.

Avant, the daughter of music producing icon Clarence Avant, helped raise at least $800,000 for Obama before becoming the ambassador to the Bahamas, according to the nonpartisan Center for Responsive Politics.

During the 2008 election cycle, Avant's father backed Obama's Democratic opponent, Hillary Clinton.

Both Avants are featured in the new Netflix documentary film, "The Black Godfather," which shows the influence Clarence Avant has had, not just on the music industry, but also in politics. Nicole Avant produced the film for Netflix.

The addition of Nicole Avant to Buttigieg's bundler list comes as other 2020 contenders, including Sen. Kamala Harris, D-California, and former Vice President Joe Biden, race to make inroads with powerful Hollywood donors.

Avant attended a recent Buttigieg fundraiser in Los Angeles at the home of actress Gwyneth Paltrow, NBC News reported.

That same week, Biden met with donors at the home of interior designer Michael Smith and James Costos, a former ambassador to Spain under Obama. Biden raised over $700,00 at that event, which was heavily attended by Hollywood executives.

Avant is the latest former Obama bundler to sign onto Buttigieg's campaign.

In April, CNBC acquired a list of more than two dozen Democratic fundraisers supporting the underdog candidate, many of whom had ties to Obama and Clinton.

Buttigieg raised $7 million in the first quarter alone and has been gaining momentum in the polls since he entered the race.

A Real Clear Politics polling average ranked Buttigieg fifth among all the candidates, with 7% of the vote. Biden continues to lead with a projected 33%.
