They say the best revenge is looking good.
A newly single Lea Michele made an appearance at the Vanity Fair And FIAT Toast To Young Hollywood celebration at the Chateau Marmont in Los Angeles on Tuesday night, showing off her amazing abs in a one-shoulder crop Solace top and wide-legged black Vatanika trousers. The event marked her first red carpet appearance since news broke on Monday that Michele and her boyfriend of nearly two years, model Matthew Paetz, split earlier this month.

While inside the party, Michele stuck to her gal-pals, including her former Glee co-star, Becca Tobin. "She seemed guarded inside ... not speaking to any guys," an eyewitness tells ET. "She stayed for an hour, holding hands with one of the girls before 9 p.m."
Michele has made no secret that she's been working hard on her fitness as of late, sharing multiple pics of herself at SoulCycle this month on social media. The 29-year-old former Glee star even worked out prior to the star-studded Vanity Fair party.
"Thank you @shapewithangela for such an amazing, powerful and inspiring class at @soulcycle this morning!!!!" she Instagrammed on Tuesday.
A source previously told ET that Michele and Paetz's split came as a "huge shock" to their friends.
"Lea and Matthew were talking about getting engaged as recently as around the holidays," the source said. "Everyone thought they would get engaged soon, but definitely not split."
