Moving on. Jenna Ushkowitz and Michael Trevino have split after three years of dating, the Glee star revealed at a recent event. According to one insider, the relationship has been over for some time.

Ushkowitz, 28, confirmed the breakup herself while attending the premiere of Glee co-creator Ryan Murphy's HBO film The Normal Heart in Beverly Hills, Calif., on May 19. When a photographer asked if the pair were still an item, she replied: "No, we're not together anymore."

The Glee actress signed autographs for fans during the interaction, and kept her head down. "That's okay, no worries," she added, smiling, when the photographer apologized. "We're wonderful."

Ushkowitz and the Vampire Diaries star, 29, made their first public appearance together at the 2011 SAG Awards. Last January, Ushkowitz posted a throwback picture of the pair on the SAG red carpet in honor of Trevino's birthday. "Happy birthday to my best friend, the one who has taught me how to laugh and love more and more everyday," she gushed.

The twosome also posed for a sexy, risque photo shoot with celebrity photographer Tyler Shields. Ushkowitz donned a red hot dress for the spread as she seductively danced with a shirtless Trevino. (Emma Roberts was a part of the project, too.)

"You can't Photoshop passion," Shields wrote on his official site at the time. "[There's] something about shooting a real couple that is so magical."
