Chart-topping singer Olly Murs gets "panic attacks" when he thinks about his records not making the Top 5.

The British star shot straight to the top of the UK singles chart on Wednesday (November 21) with his new single 'Troublemaker' featuring Flo Rida.

Despite impressing fans with his catchy tunes, Murs - whose new album Right Place Right Time is released on Monday (November 26) - still gets nervous about how well his new music will do.

He explained to new! magazine: "I get panic attacks worrying if it came in at No. 8 in the singles chart. Or imagine if my album didn't break the Top 20!

He continued: "But even my mum likes Troublemaker! And it's the first time she's said she likes something I have done."

Murs insists there is a valid reason as to why he puts so much pressure on himself.

He added: "Robbie Williams just released. One Direction have an album coming out. It's going to be a tough market! But, you know, I have good fans..."
