Rihanna 'Missing' Drake, Not Sexually Attracted to Coldplay's 'F*ckin' Cool' Chris Martin: Romantic Dating Rumors Debunked, New Collaboration Coming?

Rihanna and Coldplay frontman Chris Martin grabbed some dinner together in LA over the weekend. Several fans initially believed "sparks were flying" between the two recently-single singers. As Mstars previously reported:

Back in 2012, Rihanna paired-up with rocker Chris Martin for the hit Mylo Xyloto tune, "Princess of China" -

At-the-time, Gwyneth Paltrow's ex was psyched to work with the Barbadian songstress. He once told MTV that he wrote the song with RiRi already in mind:

"In like a dream scenario, we had a song that I'd secretly kind of written to see if Rihanna would want to sing it... nd then the rest of the band wanted to keep it, so we came up with the idea of asking her to sing it with us, and, to our great surprise, she said okay."

He continued, "She has such an amazing voice and it's so different to mine... It took a while to pluck up the courage to ask her. We did a show in Las Vegas and I met her and said, 'Do you think there's any chance?' I was very Hugh Grant-like and spluttering about it."

How cute! Well, is another collaboration in the works? Or are sparks actually flying between Martin and Drake's ex?

Over the weekend, the duo was spotted grabbing a "private" dinner together at Giorgio Baldi in Santa Monica, CA. The two were all smiles, and appeared to be bonding over something...

Check out some photos of the dinner date (at one of RiRi's favorite restaurants) here.

But turns out RiRi and Martin are NOT romantically involved. Does this mean fans can expect another epic collaboration soon?

An alleged HollywoodLife.com insider reveals that Drake's ex isn't attracted to Martin "in that way" -

"Chris is nice, a real great guy who makes her laugh but in no way are they doing anything other than talking business and music. That's it and that's what they were discussing."

The source continues, "He's cool and f*ckin' awesome but he's not Rihanna's type sexually or romantically. It was a simple business dinner and afterward, they bounced separately."

Fair enough! So, RiRi remains single... is she missing on-and-off again beau, Drizzy?
