John Stamos puts on a stylish display in powder blue suit as he joins wife Caitlin McHugh and their son Billy, five, at Wonka premiere in Los Angeles

John Stamos was joined by his wife and son at the Wonka premiere in Los Angeles on Sunday.

The 60-year-old Full House actor looked to be in high spirits as he posed on the red carpet alongside his wife, Caitlin McHugh, 37, and their five-year-old son, Billy.

For the event, he put on a stylish display in a powder blue suit teamed with a colorful, floral-patterned button-down.

The General Hospital star — who dressed up in coordinating Christmas ensembles while at Disney World with his son just days earlier — donned a pair of white sneakers and sported a pair of wayfarer sunglasses.

At the premiere of the highly-anticipated fantasy flick starring Timothée Chalamet, his son sported a maroon velvet suit with a floral top just like him.

The actress and writer looked elegant in a pastel pink cropped sweater teamed with a white waterfall skirt. 

She styled her silky brunette tresses in soft waves with one side clipped back.

The couple sported matching bright smiles as they linked arms for a quick snap.

At one point, Stamos sat down to be at his son’s level and posed with his arms wrapped around him sweetly.

Previously, Stamos and McHugh, who is 23 years his junior, met when they both guest-starred on an episode of Law & Order: Special Victims Unit in 2011.

The pair did not get together for years since she was still married to restauranteur Massimo Lusardi at the time.

McHugh and her ex finalized their divorce in 2014, and she started dating Stamos two years later.

In October 2017, they got engaged. The pair tied the knot in February 2018 — about two months before they welcomed their son, Billy.

The musical fantasy film, directed by Paul King, tells the origin story of Willy Wonka, a character in the 1964 novel Charlie and the Chocolate Factory by Roald Dahl.

In the movie, Chalamet stars as a young Willy Wonka and the story follows his early days as a chocolatier. 

Wonka will premiere next week on December 15.
