Jamie Dornan and Rita Ora may play siblings in the upcoming "Fifty Shades of Grey" movie, but apparently the two aren't close in real life at all.

The Daily Star reported that Ora, who plays Mia Grey, described Dornan, who plays Mia's adopted brother Christian Grey, as "gorgeous." She even added that him being married to Amelia Warner and having a daughter in November makes him "hotter" because he's off the market. The newspaper met up with Dornan at a BAFTA Awards after-party where they asked Dornan if these compliments flattered him.

"No I don't," Dornan reportedly said.

Next, Dornan was asked if him and Ora are now friends. The Daily Star said he "scoffed" in response.

"She was only on set for two days," Dornan said. "I wouldn't say we're friends."

Dornan must have been feeling pretty blunt that day; he shared that he is worried about "Fifty Shades of Grey" turning him into too big of a star.

"It's a strange environment, being hounded," the model-turned-actor said. "It's really hideous."

It would appear that Dornan has some reservations about "Fifty Shade of Grey" and his co-star, but recently Ora made it seem as if she had time to bond with her cast mates.

"I went from not knowing what it's like being on a movie set, to feeling like I knew them all for years, and I wasn't even there for that long," Ora told Capital FM recently. "They'd already been filming for months and months, so I came in midway through the film."

Perhaps the British singer spent more time with Anastasia Steele actress Dakota Johnson than Dornan.

"Working with Dakota was extremely fun," Ora told MTV in April. "She's just so gorgeous so it kind of distracts you a little bit, but I mean she's a really great. ... She's an amazing actress so I'm like learning things from her."

"Fifty Shades of Grey" hits theaters Feb. 13, 2015.
