We thought they were broken up -- but this joint gift definitely leaves us scratching our heads! Exes (or are they?!) Khloe Kardashian and French Montana bought the mutual friend who brought them together -- none other than P. Diddy -- an ultra expensive gift for his 45th birthday, a pearl white Escalade. Apparently a card and some balloons just wouldn't do!

While Khloe doesn't appear in the Instagram video, the music mogul thanked her (in all caps) for the expensive birthday gift. Diddy wrote, "@frenchmontana AND @khloekardashian gave me a PEARL WHITE ESCALADE for my BDAY THANK YOU FRENCH AND KHLOE. LOVE #DIDDYBDAYPARTY #DIDDYBDAYPARTYLIVE"

Diddy also added, "I HAVE A PEARL WHITE ESCALADE NOW!!! THANK YOU @frenchmontana @khloekardashian #DIDDYBDAYPARTY #DIDDYBDAYPARTYLIVE."

Khloe and French are doing little to dispel reconciliation rumors these days. The couple dated for eight months but broke up in September. However, the rapper showed up at Kendall Jenner's 19th birthday party on Monday and seemed like to have a rockin' good time with the Kardashian klan, even posing for pics with the bday girl and mama bear Kris Jenner. Maybe Kris can finally have the son she always wanted (we're looking at you Rob!).
