We've got to hand it to Jennifer Garner for being a good sport and promoting a new movie, Ghosts of Girlfriends Past, on her birthday.
Her birthday wish? For costar Matthew McConaughey not to sing to her!
The two castmates also talked about their children, including Levi's first steps (onto a surfboard) and what Jen wants most for her girls...
"I've already got him in the water," said Matthew, who plans to start training Levi on a bicycle and board before teaching him to ride the waves. "It'll kind of be up to him. We'll get him out there soon, floating around."
New mom Jen wouldn't mind if daughters Violet and Seraphina loved music, but more than anything else, "I just want them to happy," she said. "I don't care what they do. I really don't!"
Surfing versus symphonies—wonder who has the edge when it comes to parental style?
