‘He’s Managed To Keep Normal’: Holliday Grainger Reveals Long Relationship With Robert Pattinson From Harry Potter Days It looks like Kristen Stewart may have some competition, as actress Holliday Grainger recently gushed over Robert Pattinson in a new interview, praising the actor for staying “level headed” despite the constant media attention that he gets.Holliday has starred alongside Rob in Bel Ami and The Bad Mother’s Handbook and she’s said that despite the actor getting followed by fans everywhere, he’s never let the attention go to his head.”I’ve known him since his pre-Twilight days when he was a normal person and it was still like, ‘ooh you’re playing Cederic Diggory (in Harry Potter And The Goblet Of Fire),” Grainger said of R-Patz before he rocketed to Fame, according to Grazia Daily.“He’s managed to keep very level headed and normal. I don’t understand how,” he added. Holliday has spoken out about Robert Pattinson (WENN) When Rob then shot to fame, Holliday went on to recall how he took it all in his stride, saying: “I can’t fathom the idea of living a life like he lives,” adding: “On the set of Bel Ami in Budpest there would be hundreds of screaming girls there at 5am 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 6am after a night shoot. Bless him, that’s an extra level of hard.” Rob is “level headed”, Grainger said (WENN) We wonder what K-Stew would have to say about this?Despite the pair splitting last year, reports still continue to surround them both and the latest claims suggest that they have been arguing over their mutual pal Ellie Goulding.“Ellie’s really good mates with both Rob and Kristen and used to spend time with them as a couple,” a source told Now magazine. “Since their break-up, she still hangs out with both of them, but separately. Things are proving quite difficult at the minute.” Robert and Kristen look loved-up pre split (WENN) Kristen and Rob became friends with the singer when her song ‘Bittersweet’ appeared on the soundtrack for The Twilight Saga: Breaking Dawn Part 2. Last February, Kristen was spotted hanging with Ellie backstage at one of her concerts.The singer reportedly wants to invite both Rob and Kristen to watch her perform at the Coachella music festival in April, but is worried that having the former lovers in the same place might create awkward tension.“Ellie wants both her friends to be there,” the source told Now. “It’s one of the biggest events of the year for her, especially as she’s starting to make a mark on the American market. 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.”Just a year ago, Kristen and Rob attended the California music festival together. They were spotted holding hands and cuddling at the festival, but split shortly after.
