WATCH: Robert Pattinson Stays Silent Over Kristen Stewart Romance And Cheating Allegations

Robert Pattinson didn’t look happy as he walked through LAX airport this morning after arriving back from shooting new movie Maps To The Stars in Toronto and we’re not surprised as the star was set upon by the pap squad who questioned him over his attitude to cheating as well as mentioning his relationship status with ex-girlfriend Kristen Stewart.

The actor was infamously cheated on by his Twilight co-star with married director Rupert Sanders last summer and was no doubt the motivation as to why the paps were so desperate for him to comment on recent claims Lamar Odom had cheated on wife Khloe Kardashian.

The 27 year-old didn’t look like he was going to play ball though and refused to even acknowledge the existence of the persistant photographers who questioned whether or not Khloe should forgive her husband.

Stripper Jennifer Richardson, 29, claimed earlier this month that she’d been having an affair with the NBA star since meeting in Washington DC last year. Despite the allegations being out right denied by Lamar, the claims have persisted.

We doubt Rob liked to be reminded about his ex girlfriend’s infidelity, which the paps were no doubt referring to when asking him about cheating, but the actor handled the situation well as he kept his cool in the face of a barage of questions.

One photographer can also be heard asking “What’s the latest with you and Kristen?” referring to his relationship with the brunette, but even this couldn’t get a reaction out of the private star.

Neither Rob or Kristen have commented on their alleged break up, said to have happened in May even after allegations the star had moved on with BFF Katy Perry.
