Christina Applegate attended the premier of her newest film, Dogs and Cats 2 this past weekend. Christina also had an exciting announcement, that she’s pregnant with her first child! It seems like so many celebrities these days are pregnant!

For the red carpet, Christina opted for denim leggings from Frankie B. She wore Frankie B’s BFF legging in black gold. The black leggings completed her all sleek all black outfit. Apparently she loved them so much, she requested more of their jeans for her upcoming events! She’s going to be quite a stylish mom! Buy Frankie B. jeans at Revolve Clothing.
