Well, this is a unique way to pay it forward.
And while the twosome may be totally broken up, they couldn't help but come together to gift the music mogul a brand-new ride!
"I HAVE A PEARL WHITE ESCALADE NOW!!! THANK YOU @frenchmontana @khloekardashian," he wrote on Instagram while holding a delicious Cîroc pineapple cocktail in the driver's seat. "#DIDDYBDAYPARTY #DIDDYBDAYPARTYLIVE"
So why did the twosome treat the millionaire to such a special gift? Turns out these three have a history.
"Last year, French got Khloé a car for her birthday and gave it to her at a party Diddy hosted," an eyewitness told E! News exclusively. "This year, French and Khloé decided to buy Diddy a car and thought it would be fun to surprise him at his party."
The source added, "The car was parked out front and French walked Diddy outside for the surprise."
Although it was Diddy's big night, many eyes were on the Kourtney & Khloe Take the Hamptons stars who remain the friendliest of exes. Once again, the former couple proved they don't hold any animosity since their split.
"Everyone at the party saw Khloé and French hanging out, no over the top PDA but touching here and there. It was obvious they were together," a source told E! News. "They were holding hands a lot, very touchy-feely."
And while Khloé assured E! News earlier this week that she was "not dating anybody," the thought of a reconciliation between her and French remains possible.
"Things could change," Khloé shared with a smile on her face. "You never know…for anybody."
