Jennifer Aniston denies split with Vince Vaughn

Vince Vaughn and Jennifer Aniston starred together in the romantic comedy The Break-Up.

He may be in contention for worst boyfriend in the world but Vince Vaughn is still Jennifer Aniston's man, according to People magazine.

Former Friends' star Aniston taped The Oprah Winfrey show on Wednesday, telling the talk show queen she and Vaughn had not split.

Audience member Suzanne Hartigan told People Aniston made it perfectly clear she and The Break Up co-star were "still on".

The 37-year-old actress also denied recent tabloid rumours she had undergone breast surgery, explaining that when she gains weight, it goes straight to her bust.

Vaughn and Aniston's apparent split made headlines last month when American magazine Us Weekly reported Vaughn dumped the ex-Mrs Pitt because he "saw how needy she is, and it scared him off".

If the couple are still together, it may be short-lived as Vaughn was snapped kissing a mystery blonde in London this week, according to UK tabloid The Sun.
