Emma Roberts ‘back with Evan Peters’

Emma Roberts and Evan Peters are reportedly dating again.

The pair, who star on American Horror Story together, became engaged to wed in December 2013, but rumours surfaced they had called off their engagement in June.

And a source tells Us Weekly magazine their tempestuous relationship is back on once more. Emma, 24, and Evan, 28, were spotted out together enjoying a meal at Katsuya in West Hollywood last weekend, with onlookers claiming they were all smiles during the outing.

Earlier this summer, when they are rumoured to have split, insiders revealed the breakup was on good terms.

“Their three years together just ran its course,” the source told Just Jared. “They have so many great memories together but couldn’t make it work in the end. The break-up was amicable – there was no drama whatsoever. Emma and Evan are even still friends!”

It seems as if work may have inspired them to reconcile, as American Horror Story creator Ryan Murphy previously revealed Emma and Evan’s characters will be romantically hooking up together in the forthcoming season of the show.

"She comes at the end, and she has a great thing with Evan Peters at the end," told Us Weekly. "That's all I can say."

The couple have experienced pretty major conflicts in the past as Emma was arrested for domestic violence in July 2013 after allegedly assaulting Evan while they stayed at a hotel in Montreal, Canada together. He decided not to press charges against her for the attack and she was released hours after being taken into custody.

Emma and Evan started dating in 2012 after co-starring in Adult World.
