The actor broke into super-stardom playing commitment-challenged, but love-struck, Charles alongside Andie McDowell's Carrie in 1994's British smash hit romantic comedy Four Weddings and a Funeral.

The actor has been in many high profile long-term relationships, including British star Elizabeth Hurley, but has always dismissed the idea of matrimony.

"I'm not really a believer in marriage," Grant told People in 2015. "I've seen very few good examples, maybe five, in my life, but I think otherwise it's a recipe for mutual misery."

News of the pending marriage to Eberstein was revealed on May 21 when photographs of their required wedding announcement were posted in British newspapers.

Grant and Eberstein's children are 5 and 3 with a third born in March. He also has a 6-year-old daughter, Tabitha, and 5-year-old son, Felix, from his relationship with ex-girlfriend Tinglan Hong.
