SO CUTE! We have never seen daddy Bradley Cooper like this!

His adorable look alike daughter Lea was happy in dad's arms as they attended a play group with Irina Shayk Wednesday in Brentwood. This supermodel-actor duo aren't the only celebs to take their offspring to the posh play group spot -- Justin Timberlake and Jessica Biel bring their son Silas to the developmental mommy-and-me class.

But seriously, you have to check out the gallery below -- these are the CUTEST pix we've seen in a long while and they make us love Bradley Cooper even more!
