London: Robert Pattinson is struggling to get busy between the sheets with girlfriend Kristen Stewart because the couple are holed up at her mum`s place.

A source told the Sun that the duo is living with Jules because she`s going through a rough divorce from Stewart`s dad John.

"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," the source added.
