Alyson Hannigan, husband Alexis Denisof and their darling daughter Satyana went to the beach in Malibu the other day, and it looks like everyone had a blast! Satyana celebrated her second birthday last month, and Hannigan recently revealed to Parent & Child that she's torn over having more kids. "I’m conflicted," she told the mag. "I want to so that Satyana won’t feel the way I did as an only child, but I don’t want to have to share my attention. If I had another child I’m sure I would fall in love with him or her immediately. But I’m worried. We hit the jackpot with the first one. If you win the lottery, do you keep buying lottery tickets? Or just enjoy the lottery you won? "

The American Pie star added, "Sati is hilarious all the time. She has a great sense of humor. She knows she’s funny, too. Like whenever she does something cute, she gets this smile on her face and announces, 'Funny baby!'"

When asked about a certain scene in which she's on all fours with the British comedian, Garner tells Letterman:

"He was in his underwear, and they were very handsomely made. It was Russell and me, right behind him, on all fours. We did it over and over again, so I spent two days just right up against it. So I'm very familiar, in my own way, with the anatomy of Russell Brand -- and it's good."
