An OnlyFans model and groupie who once partied with Diddy has revealed the secret signals rappers use to bed women.

Sienna Grace, 30, who claims to have slept with various hip-hop A-listers, told DailyMail.com that rappers have special tricks that they use to let their entourage know which groupies they plan to spend the night with.

‘When I was backstage at a show with about ten people, [the famous rapper] put his sweater around me to be like, “This is the girl for the night,”‘ she explained, referring to one chart-topping performer.

By placing an item on the chosen girl, it lets the star’s entourage know that she’s off limits to any other men.

According to Sienna, a popular hip-hop group, consisting of three members, used a similar strategy when selecting her for a late night romp.

‘Their assistant brought me out a bottle of Ace of Spades [champagne] and that was the signal I got,’ she said.

‘And then straight after the show I was ushered to a private room.’

Sienna said that she hooked up with two members of the group in the same night, but insisted that it wasn’t at the same time.

One of the Australian model’s conquests even led her to a party at Diddy’s private home one night.

Despite the shocking charges currently leveled against Diddy – which include sex trafficking and racketeering – Sienna claims that she never really saw anything shady from the hip-hop mogul.

‘Diddy brought out his son’s birthday cake, but while he was at the party he wasn’t very present and just lurked around,’ she said.

‘I feel like if I hadn’t been there with the kids, things would have gone differently. He definitely would have tried to approach me.’

Surprisingly, Sienna said that she had never heard any horror stories about Diddy from pals until it came out in the news.

‘I’ve never heard anything about Diddy’s parties until everything came out, which was quite shocking,’ she said.

Diddy was charged with a host of sex trafficking and racketeering offenses following his September 16 arrest.

Since then, upwards of 120 victims have already come forward.

Federal authorities said Diddy – with help from a network of associates and employees – silenced victims through blackmail and violence, including kidnapping, arson and physical beatings.

The hip-hop kingpin maintains his innocence, and will face a jury in the spring.
