Rebecca Romijn On Twins: "Terrible Twos Have Already Begun!"

Now that Rebecca Romijn and Jerry O'Connell's twins are 20 months old, they are becoming quite the pair to handle

Romijn exclaims to E! Online, "The horrific, horrible terrible twos have already begun!"

She explains that daughters Dolly and Charlie literally stop in the middle of the street when they're tired of walking.

"If they don't wanna go, they'll just drop and wait, both of them!" Romijn continues. "It's like a sit-in protest. They're like, 'Nope, we're doing a sit-in.' It's so annoying!"

The actress does take it all in stride though and humorously adds, "If you're by yourself, you have to bend down on the street and pick them both up. I have never been so strong in my life!"
