Robert Pattinson and Kristen Stewart have reportedly ended their romance yet again, after three years together.
The Twilight Saga co-stars have been on-and-off with their relationship ever since Kristen was revealed to have cheated on him in 2012.
However a source told People magazine that it would not be surprising if the pair got back together again.
It comes after Robert apparently opted out of 27th birthday plans organised by his girlfriend.
Prior to the occasion their romance appeared to be strong.
They were seen in New York together after the Met Gala earlier in May and they flew back to Los Angeles together on May 8.
Robert also helped Kristen celebrate her 23rd birthday; they were seen holding hands at Coachella Music Festival in Indio, California.
Kristen had a fling with her Snow White and the Huntsman director, Rupert Sanders, last year.
She publicly apologised to her partner and they seemed to be back on less than two months later.
Before the scandal, the couple never spoke openly about dating, although it was pretty much common knowledge to fans of their movies.
The actress was recently said to be dreaming of "a normal family life" with her beau.
"After everything, Kristen just wants her and Rob to focus on the future," a source told British magazine Closer. "A normal family life together is all she dreams of."
The reason Kristen is keen to settle down with Robert now is thought to be due to his friendship with singer Katy Perry.
Katy was spotted with both Kristen and Robert at the Coachella music festival in April.
Kristen is said to be unhappy about the amount of time the 28-year-old Teenage Dream singer has been spending with Robert over the past few weeks.
