The 51-year-old actor's new love interest Sela Vave, 21, has been staying at his home for weeks, a source claimed to Radar.
"Sela is basically living at Jamie's place right now," the insider claimed. "She's been staying there for weeks, hanging with Jamie's friends and jamming in his music studio when they're not kicking back and partying on the other side of the mansion."
According to the insider, Foxx and Vave were spotted continuing their new romance at Delilah in Los Angeles on Sunday, August 18. Radar confirmed on Monday that Foxx and Holmes, 40, have officially broken up after six years of dating.
The source added that although Foxx has yet to introduce Vave as his girlfriend, he's smitten by the 21-year-old.
"Things are pretty intense between them," said the source. "He adores her and the feeling's mutual."
As Radar readers know, Foxx and Holmes kept silent about their relationship for years following the actress's tumultuous split from Tom Cruise, 57, in 2012.
But after years of attempting to hide their relationship, Holmes and Foxx stepped out together at the Met Gala in New York City this past May. The source revealed to Radar that party boy Foxx ultimately ended it with Holmes because he wanted to be with other people.
Vave is a young model and aspiring singer and actress. The brunette beauty has not exactly been shy about her recent outings with Foxx. On June 30, the 21-year-old gushed about Foxx on Instagram.
"I am so grateful to this man! Thank you so much @iamjamiefoxx for everything you do and for believing in me. #feeling blessed," she captioned a photo with him.
Additional photos seen by Radar show that the pair jetted to Disneyland on July 18 with a group of friends. They also attended an event together on July 28 in honor of Lupus awareness.
As Radar reported, Foxx and Vave were spotted getting close on Saturday, August 17, as they exited Bootsy Bellows nightclub in Los Angeles hand-in-hand.
The source told Radar that Vave and Foxx also spent this past fourth of July together at Leo's Malibu Place.
Meanwhile, Holmes remains in New York City, where she and daughter, Suri, 13, live. The famous mother-daughter duo were spotted strolling the Manhattan streets last month, where they looked more alike than ever before.
