Pharrell Williams is making music with T.I. and Kendrick Lamar, according to an image posted on Billionaire Boys Club that shows the guys hanging out in a Los Angeles recording studio.

There's no context to the photo, so we can only guess at what the trio was cooking up. T.I. sports a Hustle Gang sweatshirt, while Williams gives the "shush" expression, letting us know that he's not going to tell us anything about the music they were creating just yet.

The guys also got together in Austin last week at SXSW, where T.I. was performing a set for the BET Music Matters Showcase. Tip invited Lamar on stage to team up on a live version of ‘Memories Back Then.’ Later in T.I.'s set, he brought out Pharrell to perform 'What You Know.' Lamar, who topped MTV's 2013 Hottest MCs in the Game list, recently filmed a video with T.I. for 'Memories Back Then.'

Pharrell has been one of the hottest producers in hip-hop for more than a decade. He produced a track for T.I.'s 'Trouble Man: Heavy is the Head' album, and he's also been linked to upcoming projects by Miley Cyrus and Beyonce.
