How old is John Stamos' wife Caitlin McHugh?

John Stamos and Caitlin McHugh have an age difference of 23 years between them. The Full House actor was born in August 1963 (now 58 years of age) while his wife McHugh was born in May 1986 (now 35).

McHugh is a model signed by Wilhelmina Models. She started her acting career while starring opposite Will Smith in 2007's action-drama film I Am Legend. She then went on to appear in Blue Blood, Castle, Rescue Me, Guilty, Switched at Birth, Tomato Soup, 48 Hours to Live, NCIS: Los Angeles, and Random Tropical Paradise.

In 2014, the 35-year-old also had a recurring role on CW's fantasy drama series The Vampire Diaries.

On the personal front, she and John Stamos first crossed paths in 2011 when they starred in one episode of Law & Order together. At that point in time, nothing happened between the two of them. The duo reconnected again on the set of Fuller House, where McHugh's roommate was a cast member.

While chatting with People Magazine, Stamos recalled how he spotted McHugh on set.

“Her roommate was on an episode of Fuller House, and so she was in the audience. I walked in, I went, ‘Hey, are you stalking me?’ She was like, ‘No. That’s why I love her. She’s like, ‘What? No. I haven’t thought of you twice.'”

The duo soon started dating and got engaged in 2017. In less than two months of them being engaged, the Big Short actor revealed that they were expecting their first child together.

The pair welcomed their son, Billy, a few months after they married in 2018.

Both the actors have previously been married to other people. Before marrying McHugh, John Stamos was married to actress Rebecca Romijn from 1998 to 2005.

McHugh was also previously married to restaurateur Massimo Lusardi from 2011 to 2014.
