When Sarah Hyland stepped out on the red carpet in Las Vegas on Sunday, we couldn't help but notice how skinny the 'Modern Family' star's body looked in a vibrant red crop top and matching pants.

Compared to photos from a year ago, the petite star's arms appear thinner as does her waist. If the 24-year-old did, in fact, lose weight, it wouldn't be surprising given the stressful year she's had.

Last August, the brunette beauty went through a very public breakup with ex Matt Prokop, whom she received a restraining order against after claiming he had been physically and verbally abusive throughout their five-year relationship.

But Sarah seems to be in a much better place — at least romantically. She was spotted packing on the PDA with current boyfriend Dominic Sherwood at both Coachella earlier this month and at the Los Angeles premiere of 'See You In Valhalla' on April 21.

"We've been best friends for like two years," she recently shared of her new man. "It's just so good."
