Ariana Grande and Jai Brooks Romance: 'Problem' Singer Receives Romantic Birthday Message from Boyfriend

Now that Ariana Grande and Jai Brooks have once again reunited, the duo does not mind showing their love for each other in public. Brooks recently took to Twitter to post a romantic birthday message for Ariana.

"Happy birthdays to the most beautiful girl in the world, you are 21!!! you're my world I really love you. here's to so many more memories!" Brooks wrote on his Twitter account.

Grande and Brooks got back together in May and the couple is happier then ever.

"Ariana and Jai are great," a source told HollywoodLife "They spend as much time together as possible and are really happy."

When Grande and Brooks broke up last year, the former started dating The Wanted singer Nathan Sykes. That time Brooks had accused Grande of cheating on him.

"Yes, I was cheated on. Yes, it does suck. Yes, I was left for another man. And this happens everyday to so many people of every age, gender, race. I happen to be one of those people and I'm in a situation where I am constantly reminded of it every day. Like anyone who has been cheated on, it has been tough for me, but I'm finally ready to move on," wrote Jai on Twitter blaming Grande for breaking his heart.

However, Grande and Sykes broke-up within a few months of dating and since then Grande is back with Brooks. Meanwhile, regarding Grande's birthday plans, it is being reported that she laid back a little and chose not to party.

"Ariana doesn't go in public that much. She usually just hangs out at home with friends," the source revealed to the Web site. "They watch movies, Jai draws and they listen to music. Pretty basic."

Furthermore, it has also come to news that Grande's big brother Frankie Grande is competing on "Big Brother" season 16 and is doing really well in the Big Boss house. He won the head of the household in the series.
