"Happy birthday baby boy! In only a short amount of time we have created timeless memories. Happy birthday to a man who genuinely lives life to its fullest," the 30-year-old "Kourtney & Khloe Take the Hamptons" star captioned a romantic beach photo of them two.
"What's understood doesn't need to be explained," she added. "@frenchmontana I can't wait to celebrate life with you tonight! You deserve it!!"
Since their split Kardashian and the 30-year-old rapper have remained close. Montana even attended the birthday party of Kardashian's half-sister Kendall Jenner earlier this month, according to Us Weekly.
The duo was also present at Sean "Diddy" Combs' 45th birthday party last week, and the exes were reportedly "touchy-feely" the whole time.
"Everyone at the party saw Khloe and French hanging out, no over the top PDA but touching here and there. It was obvious they were together," an onlooker told E! News of the pair. "They were holding hands a lot, very touchy-feely."
Montana appeared on "The Wendy Williams Show" on Oct. 31, and while he did not reveal whether he and the 30-year-old reality TV star are back as boyfriend and girlfriend, he did imply that they might have reconciled.
"You know like every relationship, you break up, you make up. Right now we're on real good terms," Montana told Wendy Williams, as quoted by New York Daily News.
"We're in a real special zone right now," Montana added. "She's gonna be my baby forever."
Last month, while promoting their new reality show "Kourtney and Khloe Take The Hamptons," Kardashian also revealed to Us Weekly that she and Montana have kept in touch since their breakup. "I love memories...and I still talk to him. There's no bad blood or anything," she said.
