O.J. Simpson dressed as a gynecologist named 'Dr Seymour Bush' for his Halloween festivities in Las Vegas this year.

The notorious felon was spotted partying at the Blue Martini Lounge on the Las Vegas Strip on Wednesday night.

The 71-year-old ex-con was dressed in a white doctor's coat and had a stethoscope draped around his neck.

His coat had the words 'Dr Seymour Bush, MD' and 'gynecologist' stitched into the fabric.

As has become the norm for him, Simpson took a number of selfies with fans and partygoers at the cocktail bar who shared the images on social media.

In a video shot by an Instagram fan, the man filmed himself speaking to Simpson and saying: 'We've got O.J. here.'

Simpson pointed to his jacket and said: 'O.J.? I'm Seymour.'

When asked what kind of examinations he was giving, he said: 'I'm giving free exams. They're all free.'

The former NFL running back, who was released from prison just over a year ago after a nine-year sentence, told DailyMailTV earlier this month that he has no plans to leave Sin City.

Simpson is regularly spotted partying in Las Vegas with fans showing off their encounters with him on social media.

'You know strangely enough, I found out I fell in love with Las Vegas,' Simpson said.

'People are terrific, my kids love visiting me here. They like Red Rock, you know hiking and stuff. So, I really have fallen in love with Las Vegas.'

Following his release from Lovelock Correctional Center last year, Simpson told parole officers he would be relocating to Florida.

But he has since changed his tune, saying he is enjoying his new life away from 'negativity'.

'I'm sticking around for now. I can go to Florida, a lot of people think that I can't or that I'm limited,' he said.

'I can go live anywhere in America I want. But this is like a no-negative zone, so I'm staying in Vegas.'

Simpson was sentenced to 33 years in prison for multiple felony charges including kidnapping, assault and armed robbery back in 2003.

He served nine years of his sentence.

Simpson was infamously acquitted of murdering his ex-wife Nicole Brown Simpson and her friend Ron Goldman back in 1994. He was found liable for wrongful death by a civil court jury in 1997 and was ordered to pay $33.5 million to the victims' families.
