The speculation between Kristen Stewart and Robert Pattinson's relationship is continuing to grow.

Kristen Stewart And Robert Pattinson Spotted At Two Different Airports?

There is a possibility that the two might run into each other at Coachella Valley Music and Arts Festival this April since Ellie Goulding is set to perform there, and the singer is said to be friends with both of the Twilight stars.

On Saturday, a source told Now Magazine UK that the Anything Could Happen singer wants both of her friends to come to the festival.

Kristen Stewart And Robert Pattinson Have Skype Session?

"Ellie's really good mates with both Rob and Kristen and used to spend time with them as a couple," the source said. "Ellie wants both her friends to be [at Coachella]. It's one of the biggest events of the year for her...but she knows her mates can't even be in the same space as each other right now so she's feeling caught in the middle."

Pattinson's former co-star Holliday Grainer, who starred alongside Pattinson in Bel Ami, talked about the difficulty her former co-star is facing with all the attention he's been getting. On Thursday, The Stir reported that Grainer mentioned how her co-star managed to stay level headed.

"I can't fathom the idea of living a life like he lives," Grainer said. "On the set of Bel Ami in Budpest, there would be hundreds of screaming girls there at 5 a.m., and they would still be cordoned off when we finished. He had to move hotels because there were so many people outside his. One day he was signing autographs on the way home from work at 6 a.m. after a night shoot. Bless him, that's an extra level of hard."
