Jerry O'Connell: Rebecca Has 'Some Crazy Cravings'
"Lemonade always has to be in our fridge," husband Jerry O'Connell told PEOPLE Sunday night before participating in the Nike + Human Race in Los Angeles. "That's my job. [Also] soy cream cheese. It's crazy, right? Can't be cream cheese. Soy cream cheese. Do you know how difficult it is to find soy cream cheese? It's usually in the corner of the supermarket someplace!"
The actress – who's expecting twin girls this winter – is "getting bigger by the day," added O'Connell, noting that he's already witnessed a big change in his wife's appetite.
"Meals are not missed," he joked. "We promptly hit them and if we're a little late, then ... somebody's not happy."
As for the babies' names, the actor said he and Romijn are "definitely" leaning towards Dolly for one, since the Ugly Betty star is a big Dolly Parton fan. ("The other [name] we're not really sure," he noted.)
Before the race started O'Connell – who was one of the 12,000 participants in L.A. for the 10-kilometer race – kept himself hydrated and chatted with another celebrity runner, Jason Priestley.
To prepare for the 6.2-mile run, the dad-to-be didn't hire a personal trainer – he simply went running solo. "If you want to get in shape, I highly suggest jumping into a race like this," he said. "It forces you to get out of bed in the morning and really motivates you."
