Robbie Williams had a super awkward encounter at a concert in Australia when he accidentally flirted with a girl he didn’t realize was under the age of eighteen.

News.com.au reported he was giving a concert in Brisbane, Australia when he picked a girl out of the crowd to talk to her. He complimented her on her looks, even mentioning that it was a “secretary” type look. Williams joked he needed to make sure his browser history at home was clean before his wife noticed.

When he asked how old she was, he found out she had just turned 15 and was there with her mother. Williams replied with, “Oh sh**.” He then asked that this particular moment not go on YouTube.

He pleaded with fans, “It’ll be on YouTube, it’ll be in the newspapers, and then I’ll get arrested.”

Williams has been busy with his Let Me Entertain You tour in Australia.

Yahoo! News reported that Williams often will pause during his shows to talk to fans he chooses.

After embarrassing himself, Williams dedicated his song “She’s The One” and told her “If you can suspend disbelief and pretend I’m not 41, this one’s for you.”
