SHE became an internet sensation last month and tomorrow night viewers tuning into Michael McIntyre's Big Show can see Bolton singer Rachel Crowe get the star treatment.

The 26-year-old from Morris Green finds herself the "unexpected star" of the BBC's prime time family show, which attracts millions of viewers every week.

Rachel, whose karaoke performance at Barristers Bar in Bradshawgate last month went viral, is the latest unsuspecting member of the public to have been caught unawares by the comedian, in the most elaborate stunt to date.

Publicity shots released by the BBC ahead of Saturday night's show Michael jumping out of a sarcophagus, giving Rachel

"Rachel said: "It was the ultimate shock, I went down to London with a friend thinking I would be giving an interview to the BBC about the video going viral. I had been in The Bolton News so it all sounded so believable.

"The next day I thought I was going to a museum, doing tourist things and that's when Michael appeared."

Rachel's video of her performing karaoke generated more than two million views and won her a number of gigs ­— but never did she dream it would lead to her being a star on a popular show.

"My friend Vicky put the video on Facebook to get me as much exposure as possible, and with my mum organised to get me on Michael McIntyre.

"I was more shocked how the two managed to keep it a secret and keep it from me."

She added: "I was made to feel a real star.

"It was incredible meeting Michael McIntyre, I really like him and he was so helpful.

"It was amazing to perform, it was brilliant, I never thought I would be singing on show like that."

Viewers will have to tune in to see what Rachel performs. But when Rachel's video went viral she was approached to stage more gigs. So who know what the future holds.

"Appearing on the show is just a massive boost, it has given me a confidence boost and that I am good enough to go on shows like that."

Rachel, however, won't be among the millions tuning in tomorrow because she is performing at a private function.

"I will have to watch up on catch-up because I am singing on Saturday night."
