What does Ariel Winter love more, her new boyfriend or her butt?

The Modern Family star took to Instagram on Tuesday, Feb. 14, to celebrate Valentine’s Day with her beau Levi Meaden. And the duo, who first appeared publicly together back in December, clearly couldn't keep their hands off each other!

Happy Valentine's Day ❤ #valentines

Though the starlet claimed to have posted the pic in the name of love, all we can see are her crazy curves and bodacious bottom!

“Happy Valentine’s Day,” the brunette beauty captioned the provocative pic. The snap comes from a trip the couple took to Cabo San Lucas three months ago.

In a second Valentines-themed post, the actress is seen smelling a red rose. The shot, which was presumably taken while celebrating the holiday with Levi, features Ariel in a sheer black top and white jeans. But of course, the attention is once again focused on her derriere.

While the young couple seem to be head-over-heels for one another, their relationship has been under some scrutiny given that Levi is nearly a decade older than the 19-year-old.

Ariel is no stranger to controversy though. The teen’s Instagram account has been criticized in the past for her overtly sexual snaps.

The buxom beauty has, however, been open about past body issues, using Instagram to promote self-love. In a recent interview with Self, the actress set the record straight.

“Growing up in the spotlight was quite possibly the worst for my self-esteem,” she said. “I had a hard time finding confidence within myself. When I started, I had a completely different body than what happened overnight at 12 years old. I was stick thin, I had no chest, I had no butt — I had nothing. I was totally flat, and I was so sad about it. Then automatically, overnight, my body changed drastically. I was a D cup and had a bigger butt, and my waist was expanding. Everything was getting bigger. I automatically got this hate and judgment online.”

The teen credits her new body-positivity to her sister. “It was really helpful for me when I moved in with my sister, because she’s the type of person that is confident in her body,” Ariel revealed. "I look up to her so much… I would listen to her talk to me, saying, ‘It doesn’t matter what other people think. You are who you are. It’s not going to change. Love yourself for who you are.'"

Her budding romance with Levi comes on the heels of her breakup with Laurent Claude Gaudette, with whom she ended things over the summer.
