Jennifer Aniston's ex-boyfriend has joked that "bad manners" ended their romance.

'Saturday Night Live' star Jason Sudeikis - who had a short romance with the former 'Friends' actress earlier this year – admits he is unsure why their relationship was cut short.

He laughed: "I don't know, I don't know. Bad manners maybe?"

The TV star - who is now dating actress January Jones - then defended himself saying that not everyone gets his sense of humour.

He said: "Even joking about it gets taken out of context. It's such a weird thing to even speak about. I make what I think is clearly a joke and then some people...

"I guess it just proves that not everybody has the same sense of humour I do."

However, Jennifer didn't appear too worried about her former boyfriend as she was spotted on two romantic dates last week.

The 41-year-old actress enjoyed a cosy dinner with Lindsay Lohan's ex boyfriend Harry Morton on Wednesday (03.09.10) night before being spotted on a romantic date with 'Cougar Town' actor Josh Hopkins on Thursday (04.09.10).
