Showbiz Spy reports:
The couple are struggling to fit in bedroom action because they’re living at Kristen’s mom’s house.
“They’re living with Jules because she’s going through a rough divorce from Kristen’s dad John,” a source said.
“It’s having a bad effect on Rob and Kristen’s sex life – they’re too afraid to have any with her mum in the house.”
Recent reports claimed Rob was urged to dump Kristen.
Rob’s new pal, actor Vince Vaughn — the pair struck up a friendship recently while discussing a new film project — apparently told the Twilight star to ditch the cheating actress.
“When Rob described how he took Kristen back after she cheated, Vince said, ‘That’s a mistake – a big one,’” a source revealed.
“He told Rob he knows how easy it is to fall into a routine, but when your girl cheats on you, you should take that as a sign that you should probably end things.
“Vince said he and Jennifer [Aniston] had a great time together [with their on-set romance] but he can’t imagine settling down with someone at 26, like Rob is doing – especially someone who cheated on him… Vince told Rob he was 40 before he was done sowing his wild oats.
“Vince got him thinking, for sure… but there’s a level of comfort he has with Kristen that he’s scared of losing.”
