Despite the fact that Bradley Cooper has always kept his relationship with Renee Zellweger pretty private, The Hangover star shined some light on her this weekend!

During an interview with James Lipton on Inside the Actors Studio, Cooper pointed out Zellweger in the audience and the actress - who was seated next to Bradley's mom Gloria - stood up and gave a little wave.

X17 photogs recently snapped pics of Cooper getting touchy-feely with Jessica Biel in between takes on the set of New Year's Eve, and it appears their close friendship might've caused the breakup between Biel and beau Justin Timberlake.

Is Cooper now suddenly showing off his relationship with Zellweger to quiet those rumors?

See Renee get all giggly from the shout-out below the cut...
