In a press release sent to the media on Tuesday (July 16), the couple revealed their plans to tie the knot at the Graffiti Mansion in Las Vegas on 28 July.
The nuptials and afterparty at the Sugar Factory American Brasserie will be filmed for Mongeau's new MTV reality show.
Paul popped the question at Mongeau's 21st birthday party on 23 June, just two months after the couple started dating.
Last week, actress Bella Thorne's ex-girlfriend Tana confessed her "wedding" with social media star Paul was actually a stunt.
The YouTube influencer left fans stunned when she shared pictures of what appeared to be a wedding ring on her finger.
"Bet you didn't think we'd be engaged for this long... #ThePauls," Tana wrote, while Jake also shared several snaps of the 'ceremony' on his Instagram account, simply writing, "MarriageToday."
Tana returned to Twitter a day later to reveal the truth behind the images, writing. "'FAKE NEWS we're still engaged b***h you'll know when we have a wedding."
