What a cute celeb couple!

Dennis Quaid's much-younger model girlfriend, Santa Auzina, took to Instagram earlier this week to post an adorable new photo of herself with her famous man at California's Six Flags Magic Mountain theme park.

"#TheBeginning #LookingFresh #X2 #RollerCoaster #LA #Cali #SixFlags #Woohoo," the 30-year-old star captioned the black and white pic of herself and Dennis strapped into a ride.

The Parent Trap actor and Santa — who is 32 years his junior! — have been dating since August 2016, shortly after Dennis' third wife, Kimberly Buffington, filed for divorce from the star for the second time.

Kimberly first filed for legal separation from Dennis in March 2012 but she later withdrew the divorce papers. The couple previously tied the knot in July 2004 and are parents to nine-year-old twins, Zoe Grace and Thomas Boone.

Dennis' marriage to Kimberly was his third. The Day After Tomorrow star was first hitched to actress P. J. Soles from 1978 until 1983. He then married You've Got Mail star Meg Ryan in 1991 and the two welcomed their son, Jack Henry, 24, in April 1992. The A-list duo later divorced in July 2001.

This isn't the first time Dennis and his new girlfriend, Santa, have flaunted their love on social media. Last summer, Santa shared a photo of the two in front of Notre Dame Cathedral in Paris with her more than 2,000 Instagram followers. Since then, she's further chronicled the pair's visits to Niagara Falls, NYC, Disneyland, and Ecuador.

In a recent interview, Dennis candidly opened up about his past marriage to Meg — and revealed he's not longer "bitter" about their high-profile split. “You have to be [friendly with an ex] after a while. If you're bitter still after 15 years — and still holding grudges — something's wrong with you, not with them," he said.
