BACKSTREET Boys singer Howie Dorough made a surprise visit to Glasgow Science Centre ahead of the band’s performance at the Hydro.

The American performer took a trip up the Glasgow Tower and enjoyed a showing of Wonders of the Night Sky in the planetarium.

Veronica McShane, planetarium presenter at Glasgow Science Centre, said: "Everybody at Glasgow Science Centre was really excited to meet one of the Backstreet Boys.

"I was a big fan of the band growing up, so it was an amazing surprise to have Howie turn up at the planetarium."
