Los Angeles, California - Actor Jonah Hill seems to be floating on cloud nine!

Jonah Hill is not only doing lots of surfing these days, he also has a new lady in his life – and it appears he can't hide it from the world for a second longer!

The 21 Jump Street actor has been spotted on the streets of Los Angeles several times over the past few weeks with a blonde beauty.

On Thursday, Hill took to Instagram to announce his new relationship – sharing a selfie of the pair and beaming from ear to ear.

The 37-year-old deactivated the comments on the post – keeping both negativity and well-wishers at bay.

Hill is definitely riding the wave of love! But the big question is: Who is the new someone at his side?

Sarah Brady is Hill's 24-year-old new flame.

She is head of the Changing Tides Foundation – a non-profit organization "that empowers women to protect the planet."

While this is the first time Brady has appeared on the actor's social media, she began regularly sharing snaps of the couple in early August.

"My whole heart" and "My person," she has called Hill.

"Grateful for each and every day with you," she captioned another post of the two together.

In October, the Wolf of Wall Street actor called off his engagement to 32-year-old content manager Gianna Santos after dating for nearly two years.

It is unclear when and how he met Brady. However, it stands to reason that the lovebirds may have been introduced while surfing. They are both avid fans of the sport, while Brady is also an instructor.

The tide is high for this new couple!
