Kevin Hart and longtime girlfriend Eniko Parrish are now engaged!

The 35-year-old comedian-actor announced his engagement to Parrish Monday, Aug. 18 via Instagram. "She said YEEEEESSSSS...... #Happy #MyRib #iF-kingLoveHer," Hart wrote on the image-sharing site along with a photo of himself and his now fiancée. In the image, Parrish flaunts her engagement ring while she embraces Hart from behind.

The "Ride Along" actor took the microphone at Parrish's 30th birthday bash Monday and surprised her and everyone in attendance by popping the huge question, MTV News reported.

In an Instagram video shared by user mrrugs_, the funnyman is seen telling Parrish, "On this perfect day I chose to make the most perfect decision," before getting down on his bended knee to present her with a massive diamond ring.

The model, who has been dating Hart for five years, happily accepted his proposal.

"They're both thrilled. He knows she's the right girl," an insider told Us Weekly.

Prior to the birthday bash, Hart posted a sweet birthday message for Parrish on Instagram. "Happy Birthday to the most amazing woman in the world. Today is your day babe and we are going to party like it's 1999....I love you so much. I'm a better man because of you. P.S your old as s--t now lmao #Dirty30 #HappyBday #ThrowBackPic," gushed the North Philadelphia-born actor.

Their engagement comes a few days after Parrish addressed pregnancy rumors on Twitter. "LOL! Working on it does NOT mean right now. 'Working on it' means when the timing is right.. We will begin to plan!" she posted on the microblogging site on Aug. 14.

Meanwhile, the day of Hart and Parrish's engagement also happened to be the premiere date of the VH1 show "Atlanta Exes," which stars the comedian's ex-wife Torrei Hart.

Torrei candidly told Entertainment Tonight last May that Parrish was the reason why her marriage with the actor ended.

Hart, however, quickly took to Twitter to defend Parris. "My woman has nothing to do with my past marriage problems in any way shape or form," he tweeted. "It's almost 7yrs total of me not being with my Ex ... I guess giving a woman over 20k a month and still being there for her and being a incredible father isn't enough!"
