Joan Rivers is delighted her daughter is dating a porn baron.

Melissa Rivers has got together with Steven Hirsch, the founder and co-chairman of the adult entertainment company Vivid Entertainment, and her comedienne mother insists its great because she now gets discount on the company's X-rated products.

Joan told TMZ.com: "First of all, he came he saw my daughter, and that was it - he's crazy about her. He makes a great living and he's Jewish and a businessman, and I'm 78 years old and now I get a discount on lubricant."

Joan insists she has no problem with Steven's company - which has released several celebrity sex tapes, including 'Kim Kardashian Superstar', 'Pamela Anderson & Tommy Lee: Hardcore & Uncensored' and 'Kendra Exposed', which features Kendra Wilkinson - and other people shouldn't be outraged by it.

She added: "He's a businessman - for all these people who say stay away from porn - let's look on their computers? He's crazy about her, as he should be."

When asked how Melissa and Steven, 50, met, Joan joked: "Well, I went to auditions ... no, a friend fixed them up.

"A friend said to Melissa literally, this man has seen you and he knows you just broke up with this guy and he's a businessman and he'd love to meet you. He's smart and Melissa took a chance and that was it."

During his time in the porn business Steven has been executive producer of produced films including 'Other Men's Wives ' and 'The Price of Desire' and starred in documentary TV series 'Vivid Valley'.
