Ben Stiller enjoyed "feeling Penelope Cruz's bosom" on 'Zoolander 2'.
The 50-year-old actor is "shocked" the stunning star - who has children Leo, five, and Luna, two, with husband Javier Bardem - agreed to appear in the fashion comedy sequel because she is so talented, and he is thankful the role came along at the right time for her.
He said: "It was an excuse to feel her bosom... I'd then have Javier glaring at me from behind the camera!
"I'm still shocked Penelope agreed to be a part of this, she's a world-class Oscar winner with this unbelievable back catalogue of astounding roles.
"She's so funny, has this subtle timing and we were so lucky she was looking to do an American comedy."
'Zoolander 2' comes 15 years after Ben and Owen Wilson starred in the first movie as models Derek Zoolander and Hansel, and Ben is already looking ahead to the third installment, though it'll be a long time coming.
He told Britain's OK! magazine: "I'm digging this whole 15-year break. I'm 50, so it would be very interesting to check back on him at 65."
