George Clooney is saying goodbye to his one-time bachelor pad … because he just sold his Los Angeles estate, where he used to entertain like crazy.

Our real estate sources tell us … the actor’s 6-bedroom mansion in Studio City’s Fryman Canyon is changing hands for $14.5 million.

George owned the home for nearly three decades … he bought it back in 1995 from Stevie Nicks for $2.2 million … and hosted many big parties and large gatherings over the years.

The sprawling estate features 7,000 square feet of living space spread among a main house and several guest houses on a 3.1-acre plot. It’s got all the bells and whistles, including a tennis court and a pool.

Once George settled down with Amal Clooney, the space transitioned from bachelor pad to family home … and Amal told Vogue in 2018 the property was the couple’s “private oasis.”

The place is pretty secluded … it’s tucked behind a bunch of trees, offering tons of privacy.

The sale is a big change for George and Amal’s real estate portfolio … which also includes homes in Italy, France and New York. So they’ve got other places to lay their hats.
