Piers Morgan is off the market!

The America's Got Talent judge tied the knot with British columnist Celia Walden Thursday in London.

Though Morgan's fellow Britain's Got Talent judges Simon Cowell and Amanda Holden were not in attendance, that didn't stop them from wishing the 45-year-old Brit well on the his big day.

"Piers got married today!! I could not be happier for my lovely friend!" Holden Tweeted. "Celia his wife is fabulous! Big party for us lot very soon."

In December 2009, Morgan proposed to girlfriend of four years. "I know what you're all thinking: 'How lucky is she, right?'" Morgan joked on the Today show.

After handing her a gift, he popped the question. "She opens the present. It's a first edition of 'Marry Me' by her favorite author," he said. "There were tears."
