Rebecca Romijn and Jerry O'Connell each had a twin on their hip in LA yesterday. The parents stopped by an indoor playground with their daughters, Dolly and Charlie, who looked adorable in matching t-shirts. Rebecca recently chatted about her 2-year-olds during an appearance on The Rachael Ray Show, saying that, though her kids could not have more distinct personalities, they're both daddy's girls. The busy mom has been sticking to the small screen since the birth of her children, but she made her mark in movies like 2006's X-Men: The Last Stand. The film's prequel, X-Men: First Class, comes out next month, with Jennifer Lawrence taking over Rebecca's former role of Mystique in what is anticipated to be one of the best action flicks of the Summer.
