Rita Ora and boyfriend Calvin Harris began dating last year and have seen their individual careers continue to soar. Harris, 30, is currently doing a two-year DJ residency in Las Vegas. Ora, 23, is preparing to release her second album and will be seen starring in the upcoming Fifty Shades of Grey movie.

Ora said to the Sun, "I've never been happier. He's cool though, you know. I'd love to tour with him.

She added, "It would be cool to have him there but he has his own shows to do."

Ora's newest single 'I Will Never Let You Down' was produced by Harris and is currently number one on the Vodafone Big Top 40. Ora said that while they've worked together on four songs for her upcoming album, she never asked the Scottish DJ to lend his hitmaking talents.

"It all happened naturally, nothing was ever asked. We play each other music the whole time," Rita explained. "I appreciate his ears, because he's one of the best songwriters and I like to know his opinion."

As for touring together, Harris seems to think distance makes the heart fonder. "We see each other like four days every two weeks, so it's like an issue when she's around. We'd probably get sick of each other if we had a whole month (together)," Harris told the Daily Star about his relationship with Ora.

Rita Ora was at the Met Ball in New York City earlier this week, where she met The Dark Knight Rises star Anne.

"I don't often get those pinch yourself moments, but that was up there," Rita told The Sun this week. "I ended up chatting to Anne Hathaway, she looked amazing."

Ora added, "She said she was a big fan of mine and I was gob-smacked. I mean, I've watched The Princess Diaries a thousand times. It's my go-to film."
