News: Rihanna vs. Ellie Goulding -- Potential Collabo?

If you were one of the lucky festival attendees at this years' V Fest over the weekend, you may have caught redhead-no-more Rihanna's set — and spotted UK darling Ellie Goulding watching the performance in the best seat in the house!

Reportedly, the pair swapped phone numbers when RiRi invited Ellie backstage in one of her, uh, 15 dressing rooms. The two were said to have hit it off, and the S&M hitmaker offered an up-close-and-personal spot to Ms. Goulding to watch her perform. Now, there's tons of speculation that the two ladies will collaborate in the near future. 

Check out Ellie's cover of "Only Girl (In The World)" on BBC Radio 1 — hopefully their collabo is just as awesome!
