TV mogul Ryan Seacrest has denied allegations of misconduct from his former stylist, saying that he is an "advocate for women".

Variety reports that the 42-year-old star, known for hosting shows such as American Idol and Kelly and Ryan, was accused of behaving inappropriately towards the unidentified woman a decade ago when they worked together at E!. Details of the alleged encounter are currently unknown.

The entertainment news company has since launched an internal investigation into the allegations, which Seacrest denies.

"Recently, someone that worked as a wardrobe stylist for me nearly a decade ago at E! News, came forward with a complaint suggesting I behaved inappropriately toward her," Seacrest said in a statement to Variety.

He said he was "truly sorry" if he made his accuser "feel anything but respected" and that he would co-operate with the investigation.

"I dispute these reckless allegations and I plan to cooperate with any corporate inquiries that may result. I treat all my colleagues with kindness, dignity, and understanding, as this is a principle that's core to who I am.

"Throughout my 25 years in the entertainment industry, the majority of my co-workers have been women, and I've endeavoured to foster a positive work environment of mutual respect and courtesy, as that's how I believe it should be.

"I'm distraught that anyone or any situation would call that into question. I'm proud of my workplace reputation, and believe my track record will speak for itself. I'm an advocate for women. I will continue to support their voices."

The TV and radio personality is the latest star to be accused of misconduct in the wake of the Harvey Weinstein scandal.

The shamed producer has been hit with allegations of sexual harassment and assault by more than 30 women including Rose McGowan, Cara Delevinge, Kate Beckinsale and Gwyneth Paltrow.

While he has apologised for his past inappropriate behaviour, he denies allegations of non-consensual sexual activity.
