The former 'Friends' star recently revealed that she has put on a couple of pounds due to Theroux, 42, who is an amazing cook, reported People magazine.
"Like, hello! Carbonara. It's a killer. The last couple of years since meeting this man have made me gain a couple extra pounds. But it's all worth it," she said.
Even though the 45-year-old actress occasionally likes to indulge, she is still very dedicated to her fitness routine.
"It catches up to you, and you take care of it. But it's still fun. It was all in the name of love!," she added.
