Heartbreak is tough, even when you’re Robert Pattinson. The future of his relationship with girlfriend Kristen Stewart is still hanging in the balance. The two seem to be on the outs again, and a certain rainbow-haired pop singer might be partly to blame!
 
So if Rob does decide to pick up the pieces and move on, here's that lucky lady and four others who could help the Twilight star mend his broken heart:

Katy Perry
Rob helped Katy through her divorce with comedian Russell Brand, the two were spotted partying together recently, and a source told E! News that Katy was a factor in Robsten's breakup. We could see their mutually supportive friendship blossoming into something more in the future. 

Amanda Seyfried
The Les Miserables actress has been spotted out and about with several different guys, from Dexter star Desmond Harrington to her Lovelace co-star James Franco. If Rob is looking for a flirtatious friendship or something not too serious, Amanda could be his girl.

Jena Malone
OK, maybe we’re a little more excited about the cross-franchise promotion opportunities this couple could have. Cast as Johanna in The Hunger Games: Catching Fire, Jena would jibe well with Rob’s Twilight fame.

Emma Watson 
Could it be more perfect? Both Emma and Rob are high-profile British actors known for starring in two wildly popular franchises. And let’s not forget Rob’s brief but crucial role as Cedric Diggory in Harry Potter and the Goblet of Fire. Emma has been seen recently classmate from Oxford University, but we think Rob could give him a run for his money.

Rooney Mara
Knowing Rob’s type, you can’t get much edgier than this Girl With the Dragon Tattoo star. We’re sure Rooney’s not as fierce as Lisbeth Sanders in real life, but she’s definitely an actress on the rise who can keep up with Rob’s superstar status.
