Paul McCartney is proving to be a pretty popular guy with pop stars these days. It began with Kanye West's too-cute mama-memorializing "Only One." Next up was Rihanna for the new hit "FourFiveSeconds," also featuring joined by Mr. West (does Yeezy have a Beatles thing or what?). 

Now new evidence reveals that Lady Gaga is next up on the list of modern stars to ask the legendary songwriter for a helping hand. The news came via Instagram. The ARTPOP superstar posted two pictures, one with Sir Paul and another with the pair surrounded by a team of brass musicians.

"Always a good time with my buddy. I'll never forget when he called me last year to work and I hung up the phone cuz I thought it was a prank!" Gaga wrote on one image. "Had a beautiful session with Sir Paul McCartney and friends. Working on one of his many secret projects! Killer musicians, vibe, and lots of laughs," she shared on other snap.

After recording with Tony Bennett last year, we're confident Gaga knows how to hold her own next to a legend.
