from www.dailymail.co.uk – As the founder of Vivid Entertainment, Steven Hirsch has brokered deals for the sales of the sex tapes of stars including Pamela Anderson and Kim Kardashian.

But the 50-year-old’s X-rated career clearly isn’t something which bothers his rumoured new girlfriend, Joan Rivers’ daughter Melissa.

Melissa, 43, and Hirsch are said to have been dating for the past two weeks after being introduced by mutual friends.

A source told TMZ.com: ‘The relationship is going great.’

The relationship comes just months after Melissa, who is Joan’s only daughter, split from her long-term boyfriend Jason Zimmerman after discovering he was featured on an adult website.

She said following the split in September: ‘Unfortunately, after almost three years, Jason and I are no longer together.

‘I am still trying to process what has come to light over the past few days and I hope that you will respect the privacy of my son and I while we heal.

‘Luckily, we are ‘Rivers’ and always bounce back! Thanks to all my supportive fans, friends, and co-workers for their love and support which is carrying us through.’

Melissa, who stars with her mother on reality show Joan & Melissa: Joan Knows Best, is divorced from horse trainer John Endicott.

She has an 11-year-old son Cooper with Endicott.

As well as her TV show with her mother, Melissa executive produces the hit E! show Fashion Police.
