The news comes just two months into the YouTubers' relationship.
The YouTube stars took the next step in their relationship when Paul proposed to Mongeau in Las Vegas over the weekend. The pair was celebrating Mongeau's 21st birthday at Drai's Nightclub with friends when Paul, 22, brought Mongeau on stage to pop the question with a Ring Pop.
After Mongeau accepted Paul's proposal, photos of the couple popped up on screens around the club and they were joined on stage with a three-tiered cake reading "Will you marry me, Tana?" When they sat back down at their table, Mongeau was spotted wearing her actual engagement ring.
Mongeau showed off her giant ring on her Instagram Story, and then confirmed she and Paul were indeed engaged on Twitter. "JAKE JUST PROPOSED," she wrote early Monday morning. "I’m....... engaged.................."
The pair's relationship has certainly been a whirlwind. Mongeau, who previously dated Bella Thorne and Brad Sousa, started dating Paul just two months ago. "It’s not [a joke]," she tweeted of her and Paul's engagement. "I’m engaged. holy f**k."
It's been a big weekend for Mongeau, who received a Mercedes G-Wagon from Paul as a birthday present just one day before their engagement. "Never give up on your dreams, kids. THANK U BABY," she captioned a photo of herself and Paul posing with the car, which costs upwards of $125,000.
In a recent interview with ET, Paul admitted that his older brother, Logan Paul, actually went on a date with Mongeau before they started dating. Watch below.
