Ariana Grande seems to have things going for her these days: a successful career, a blossoming fan base, and a blooming love life.

According to an article by Perez Hilton, Ariana and her beau, Big Sean are all loved up, with tons of photos on Instagram to prove it. Someone shot a photo of the singer and the rapper together while she was sprawled on his lap, and her caption said it all: "happiest."

Hollywood Life revealed that the photo was in fact taken in the back of an SUV while the couple was riding through New York City, and the 21-year-old isn't shy about telling the world how happy and content she is with her life and her man.

The adorable photo of the couple was only up for a few hours on Ariana's page when Big Sean posted the same one in his own Instagram account. Yep, they are all loved up.

Apparently, their PDA did not stop with the photos. According to MTV, their love was also on full display when they both performed during the Jingle Ball at the Staple Center in Los Angeles last December 11. The couple did another collaboration for their new duet called "Best Mistake," which they previously performed for "A Very Grammy Christmas" a few weeks back.

According to the International Business Times, the couple is planning to be engaged by the new year, a source telling Life & Style that the couple have been talking of marriage, adding that "She [Ariana] is hoping for a ring this Christmas. She knows they're young, but she is head over heels in love with him. It's very serious."

Her wish just may come true, too. The source for the magazine also stated that, "Sean is completely smitten with her and adores her," the insider adds. "He's always telling her how happy he is he didn't end up marrying his ex, Naya Rivera, because Ariana is his true love."

The pair is making sure that they make the most out of their time together because Hollywood Life noted that they will soon be spending more time apart as Big Sean spends the rest of the week in NYC, while Ariana is performing across the country for more Jingle Ball appearances that include Washington DC and Sunrise Florida.

What do you think of the adorable couple, are they really going to be tying the knot soon?
