Rebecca Romijn and Jerrry O'Connell's twins are only 20 months old, but they've already got street cred.
Of sorts...
"The horrific, horrible terrible twos have already begun!" Romijn tells us.
How so?
She and her Piranha 3D hubby say daughters Dolly and Charlie, who will turn 2 in December, have a funny way of showing them they're tired of walking.
"They just stop in the middle of the street," O'Connell reveals.
"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!"
However, there is an upside to their antics. Romijn says that it's actually become a good way to stay in shape.
"If you're by yourself, you have to bend down on the street and pick them both up," she smiles. "I have never been so strong in my life!"
