Nicola Formichetti, Lady Starlight, Fernando Garibay, Jimmy Iovine and Wale? While many can claim that they've contributed to [artist id="3061469"]Lady Gaga[/artist]'s musical success, D.C. rapper Wale insists that he wants full credit -- jokingly, of course.

"I made her whole career," he said Wednesday (May 25) on "RapFix Live" of Gaga, who is the focus of MTV's documentary "Lady Gaga: Inside the Outside," airing Thursday at 9 p.m. and 11 p.m. on MTV.

In 2009, Gaga appeared on Wale's "Chillin'," the lead single off of his debut album Attention Deficit. Though Gaga had already released her own debut a year earlier, it took some time for The Fame to earn the multiplatinum success it has now, giving Wale the lane to joke about staking claim to her meteoric rise.

All jokes aside though, Wale told host Sway that his recording session with Gaga was one that he'd never forget. "It's one of those things; it's a moment that I hold near and dear to me, 'cause she's probably the most famous person in this generation right now," Wale said. "I don't think she'd probably ever get on a rap record again."

Wale remembered traveling from D.C. to New York after a long night of partying for the session with LG. "We got here and I was kinda faded a little bit still. She was in the studio with this big rubber ribbon in her hair. She was like, 'Marc Jacobs made it for me; it's a one of one.' "

At first, the "cultural differences" were tough for the two artists to get past. In an effort to warm up to each other they made small talk about their respective record deals with Interscope. "It took a while. Once we finally got the ball rolling, it was almost time to go," Wale said. "It was natural though. It's wack when you get in the studio with somebody and it's automatically music time -- it feels fake. We were trying to feel each other out."

The MMG MC also remarked that Gaga was a hard worker and laid five different hooks for his Cool & Dre-produced single. "I still got the vocal sessions, you might here another song with her vocals on it," he laughed.
