Demi Lovato
and Wilmer Valderrama are still going strong!

The cute couple attended Nick Jonas' "Jealous" Top 40 Radio Celebration Party at The Ivy in Los Angeles on Tuesday.

The "Heart Attack" singer and her "That '70s Show" beau both looked super stylish at the event. Lovato stunned in her sheer fishnet crop top, matching pencil skirt and wore her hair in a side-parted updo, while Wilmer looked handsome in a blue turtleneck, black blazer and khaki pants.

While the cute couple rarely make red carpet appearances together, they seemed stronger than ever at Jonas' bash.

Demi and Wilmer have kept their romance pretty private in the past, but just over the past few months, the 22-year-old has started to share more pictures of them together on social media. They even recently adopted a super cute pup over the holidays.

Nick and Demi likewise have a close relationship -- the Jonas Brother recently told Capital FM, while playing a game of "Lips, Wife, Leave" with Lovato, Selena Gomez and Miley Cyrus as his choices, that he would marry the "Skyscrapers" singer, kiss Gomez and ditch Cyrus.

We think it's great that the brunette beauty and the 34-year-old actor have finally gone public with their romance!
