Gwyneth Paltrow has been married to Coldplay's Chris Martin for 10 years and admitted on Thursday's "Good Morning America" that it gets tough.

"It's not easy to be married for 10 years, and we definitely have big ups and downs. We laugh it out," the 40-year-old "Thanks for Sharing" star tells ABC News' Nick Watt. Laughing, she adds, "So far we're sticking it out."

The actress got a bit of flack when she was deemed People magazine's World's Most Beautiful Woman this year, but says she "doesn't engage" with her critics. Saying of the honor, "I'd just turned 40, and I've got two kids and I thought, 'Oh, this is so nice for all the mothers in the world.'"
