Robert Pattinson is reportedly "still broken up" over his split from Kristen Stewart.
The 28-year-old actor - who separated from the 'Snow White and the Huntsman' star after she had an affair with director Rupert Sanders in 2012 - is believed to still have feelings for his ex.
A source revealed: "Everyone knows he is still broken up over Kristen."
Robert's new girlfriend, singer FKA twigs, is supposedly feeling second best to Kristen.
The source told RadarOnline.com: "I am sure that this girl is worried that she is a rebound."
Meanwhile, a second source previously admitted that the 'Twilight' star has "no problem" introducing his new girlfriend to his ex.
A source revealed: "Rob and Kristen are inevitably going to cross paths. Tahliah (FKA twigs) is a huge part of his life and will be living with him when they are in LA.
"Rob has no problem at all introducing them to each other."
Despite the rumours that Robert is pining for his ex-girlfriend, other reports suggest that he is "falling in love" with the 'Two Weeks' hitmaker.
The insider said: "[Rob] wasn't even that disappointed that his film ['Idol's Eye'] got pushed because it means he can spend more time following her around on tour, he's her number one fan.
"They're very serious, Rob's only seeing her, he's not dating anyone else or even looking at other girls. He's really happy, they're falling in love, he's totally wrapped up in her."
