Last night, April 17th, the beautiful and talented Jennifer Lopez locked in studio time finishing up her album with super producer RoccStar in a session which lasted well into the late hours of the night.  RoccStar has worked with the likes of Beyonce, Usher, Robin Thicke, and Chris Brown in the past, and now he's used his talents to help JLo craft some serious bangers for her new album which is scheduled to be released on June 17th.  

The pair was photographed hard at work in the studio together and they each posted photos from the session to their Instagram accounts.  Check out JLo and RoccStar in the studio in Hollywood, California, above.
