Sexy Stars: Erika Jayne takes the plunge in daring dress while Julianne Hough looks like a total princess

Stars were feeling confident on the red carpet this week!

With frigid winter temps seemingly behind us, stars celebrated the first week of spring with some skin-baring outfits.

"Dancing With the Stars" contestant Erika Jayne showed off her enviable dancer's bod in a figure-hugging black gown with a plunging neckline, while fellow judge Julianne Hough looked like a total princess in a dreamy dress.

Demi Lovato looked lovely in a bright multi-colored frock with some heels to match. The songstress finished her look with a bright red lip.

But of course, red carpet queen Jennifer Lopez (let's just call her Slay-Lo already!) turned up the heat in a sexy LBD with a dangerous thigh-high slit to promote her new NBC show "World of Dance."
