Alyson Hannigan

Don’t mess with Alyson Hannigan and her pickles! The pregnant How I Met Your Mother star has a special craving for the snack.

"If I bring the wrong ones home, she won’t touch ’em," said Hannigan’s husband, actor Alexis Denisof, last night at the Best Friends Animal Society’s 15th Annual Lint Roller Party in Hollywood. "It has to be the exact right ones. They’re the sweet, kosher pickles. They can’t be the pepper, garlic or whatever—it has to be the right one."

Denisof also revealed some baby names. Well, names they’ve already ruled out...

"Our plan is to each make a list and give it to the other one, and then we kinda sleep with it for a while," Denisof said. "We start eliminating names from each other’s list, and somehow we’ll compile a master list."

And as far as the already eliminated names go, "She ruled out Bruce, which I was opting for, and I also got overruled on Dennis," he said.

With no mention of any female names, does that mean the duo is having a boy? "We know the gender, but I don’t think I’m allowed to say," Denisof said. "Alyson didn’t give a clearance."

As for Alyson, she is loving pregnancy. "I love everything. I just feel great, and I can feel the baby move, and I’m just over the moon!" she cooed.

Also at last night’s soiree were Jodie Sweetin, Rene Russo, Cloris Leachman and Emmy Rossum.
