Hilary Duff: I Lost "30 Pounds" After Giving Birth to Son Luca in 2012

Hilary Duff and Mike Comrie have their hands full with little Luca, their 11-month-old baby boy. The couple made a joint appearance -- sans their son -- at the PGA Tour Wives Association 25th Anniversary Event in Santa Monica, Calif., Feb. 11. "They were looking into each other's eyes constantly and smiling goofily at each other," an attendee tells Us Weekly. "They are so cute together."

Duff would certainly agree. "We're really good," she told Us of life with Comrie, 32. "He's always doing everything for me. He is seriously the sweetest, most thoughtful, romantic person. He puts up with me, so I appreciate that!"

Though things are better than ever for the couple, they have no immediate plans to give Luca a sibling. "I'm not trying to have a baby anytime soon!" Duff exclaimed.

It's not too surprising, given how hard the Lizzie McGuire actress worked to get her post-baby body back in shape. "I feel elevated and better about myself when I do work out," said the star, who slipped on a pair of 26-inch jeans in December 2012.

"My one trainer helped me lose a sh-t ton of weight," Duff revealed. "I lost like 30 pounds. His name is Gabe Johns and he is amazing. He's a boxing trainer and he comes to my house. I live in the canyon, so we just run. He runs my ass up and down the hill."

The Raising Hope guest star added, "We do some circuit stuff and boxing, which is a lot of fun and you get out a lot of sh-t that way. The other trainer I want to give a shout out to is Vivica, and she has been my Pilates instructor for like seven years. And Harley Pasternak, who is like a genius. He is a sculpting genius."

Duff also praised her hockey player hubby for being a hands-on parent. "I think it took like a good five months for us to be in a nice rhythm -- but not in a negative way at all, just in a new way," she said of being first-time parents. "He's the best dad. When I see him with Luca, it's beautiful, it's like happy, it's bliss, it's wonderful, so it's really, really sweet."
