Kristen Stewart's heart hurts seeing Robert Pattinson with Suki Waterhouse

American actress Kristen Stewart is reportedly unhappy after reports emerged that former boyfriend, Robert Pattinson is dating Suki Waterhouse. The 32-year-old actor and the 26-year-old actress/model were recently spotted kissing and having a good time together in London.

The couple also enjoyed the screening of Mamma Mia! Here We Go Again. According to a report in Hollywood Life, the Snow White and the Huntsman star, who is rumoured to be dating model Stella Maxwell, still misses Pattinson.

"Kristen still thinks about Robert all the time and kind of misses him too, in a weird way so it makes her a little uncomfortable whenever she sees him dating someone new," a source said.

"Despite everything Kristen and Robert went through together, she still has strong feelings for him. Robert was a big part of Kristen's life for many years so seeing him with Suki hurts," the insider added.

The source went on: "She hopes Robert finds happiness but she doesn't care to know or hear about it. She does not like seeing Robert looking in love with someone new."

In 2012, Pattinson ended his relationship with the 28-year-old actress after it was confirmed that she had an affair with British director Rupert Sanders. Stewart and the father-of-two, who worked together on Snow White And The Huntsman, were photographed kissing in Hollywood Hills.

Meanwhile, Stewart had revealed she might consider dating men again. During an interview for Harper's Bazaar UK in 2017, she talked about her sexuality. She said: "Yeah, totally. Definitely... Some people aren't like that. Some people know that they like grilled cheese and they'll eat it every day for the rest of their lives. I want to try everything. If I have grilled cheese once I'm like, 'That was cool, what's next?'"

"I've been deeply in love with everyone I've dated. Did you think I was faking it? I've always really embraced a duality. And really, truly, believed in it and never felt confused or struggling. I just didn't like getting made fun of," she added.
