Matthew Broderick Is Nervous About Having Twins

Matthew Broderick and Sarah Jessica Parker are reportedly "overjoyed" to be welcoming twin daughters this summer, but the expectant dad admits to feeling a few jitters!

"Oh man, I'm nervous just even thinking about it," Matthew told David Letterman this week.

"You know, I've asked people, 'What's it like to have twins?' One father said, 'I don't recommend it,' but the rest have been very positive," he says.

The girls will be joining the couple's son James, 6, who is looking forward to being a big brother.

"He's pretty excited," Matthew reveals. "He said, 'We have to get a lot of princess toys.'" Aw!

Matthew, 47, and Sarah Jessica, 44, shared the happy news last month that they are expecting twins via a surrogate.
