Former television presenter John Leslie has gone on trial accused of sexually assaulting a woman at her hen party in an Edinburgh nightclub last year.
The 53-year-old is accused of putting his hand down her trousers as they danced at the Atik club last June.
Leslie is in trial at Edinburgh Sheriff Court under his real name John Scott and denies the charge.
The woman, who cannot be identified, was the first to give evidence at the trial. She said she saw Leslie when they entered the club and recognised him from television, particularly Blue Peter, and had spoken to him during the night.
While dancing with friends and a stag party later in the night she said Leslie approached her and said "be careful, you're getting married".
She said she thought he was being "protective" and suggested they dance together.
The woman said: "We'd been going in circles then he pulled me closer. I did feel uncomfortable but thought I was maybe reading too much into it."
She said she gave her friend "a look" to make her aware she was uncomfortable, adding: "After that I felt his hand go down my trousers at the back.
"I didn't know how to react. I made even more of a look to my friend because I knew I needed to be out of that situation."
The woman told the court a friend pulled her away and then danced briefly with her hen party to "pretend it hadn't happened".
She added: "But then I got really upset so moved to the booth. I asked my friend something like 'why did he think he could do that or what did I do to make him do that?"'
She went outside with a friend and her sister-in-law who said they should tell someone, the court heard.
She said they told a female bouncer and later a police officer at the nightclub who took her to a station to make a statement.
The woman said it had impacted on her relationship with her husband, friends and work.
She said: "It's been one of the toughest years of my life when it should have been the happiest."
Under cross examination by defence lawyer Derek Ogg QC, she cried and said: "I don't know why anyone would think I made this up. I have nothing to gain from it."
The trial continues on Friday.
