'The Vampire Diaries' Star Michael Trevino Dating Nina Dobrev Following Split from Girlfriend Jenna Ushkowitz?

"Glee" actress Jenna Ushkowitz and "The Vampire Diaries" actor Michael Trevino have reportedly ended their three year relationship.

The reason for their split is yet unknown, but Ushkowitz and Trevino are said to have parted ways amicably.

Ushkowitz, who plays Tina on the musical drama "Glee," revealed her single status during a May 19 red carpet event when she was asked about her relationship with Trevino by a fan.

"No, we're not together anymore," she said, reported HollywoodLife.

Reports have it that the couple have been together since 2011. Although they haven't opened up about being a couple, Ushkowitz have posted online several pictures of them together, hinting that they were dating.

In January, she posted online a photograph of them at the Golden Globes, and captioned it saying: "Happy birthday to my best friend, the one who has taught me how to laugh and love more and more everyday. Congrats on another year around the sun."

Celebrated photographer Tyler Shield, who did a photoshoot with the couple in 2011, wrote on his website that the couple had amazing chemistry.

"You can't photoshop passion something about shooting a real couple that is so magical! Ever had a kiss in the rain?" he wrote.

Meanwhile, speculations are rife that the two might have called it quits because of Trevino's increasing closeness to his "The Vampire Diaries" co-star Nina Dobrev.

Trevino and Dobrev sparked dating rumors last month after the actress posted a picture of them hanging out together. "There's a method to our madness #danger" Dobrev wrote alongside the Instagram picture of herself and Trevino enjoying a game of bowling.

Citing a Star magazine source, an Entertainmentwise report that was published in April stated that Dobrev and Trevino had been hooking up ever since filming of season five of "The Vampire Diaries" came to an end in April.

"It's pretty casual right now. But Mike likes her a lot and would love for things to get more serious," the source explained.

However, several fans of Dobrev, who wanted her to get back with former beau Ian Somerhalder, blasted these rumors saying that people shouldn't jump to conclusions just because two actors are hanging out together.

"They are good friends. Geez. Calm down people," one Instagram user wrote. "'Nina Dobrev is reportedly dating her 'The Vampire Diaries' co-star Michael Trevino, who plays Tyler Lockwood in the CW series.' HELL NO!!!" one Twitter user said., while another added: "Omg people, Nina has posted just one pic of Michael Trevino NOTHING IS GOING ON lol."

Meanwhile, Celeb Dirty Laundry reported that Somerhalder has requested an early release from "The Vampire Diaries" series as he wanted to get away from the awkwardness of shooting scenes with Dobrev, and this might be why his character, Damon, was killed off in the fifth season's finale.
