Liv Tyler is finally pleased with the way she looks.

The former model has said she spent her entire life worrying about her weight - until she became a mother.

The beautiful actress admits she was body conscious and constantly on a diet but everything changed after she gave birth to baby son Milo, now two.

"The Lord of the Rings" actress told Glamour magazine, "I've been a model and actress since I was 14, so I've been on a diet my whole life. But once I gave birth, I didn't want to think about myself or feel insecure about my career, I wanted to think about my child. So I stopped worrying about diets."

Liv, now 29, has also revealed she felt more confident after getting pregnant and successfully delivering Milo.

She added, "I really felt I'd done something well, and I can't say that about anything else in my life."

Despite ridding herself of her weight obsession, Liv - who is married to Royston Langdon, 34 - had to lose 10 pounds for her role in new movie "The Strangers," set in South Carolina.

She said, "Filming was incredibly intense. We were supposed to be out of breath in every scene, so I would run around the stage to achieve that. The weight just fell off me. I just went to Marc Jacobs and I bought a red dress in a size 4. I've never been a size 4 in my entire life! It's strange though because I've been eating like a pig! I think it's because I hired a chef on the set of "Strangers" to cook for me. I ate a lot of vegetables and protein."
