Adam Lambert has opened up about Bruno Mars, calling him a "funny guy".

The pair worked together on Lambert's 'Never Close Our Eyes', which came off of his latest album 'Trespassing'.

Speaking to the Daily Star, Lambert suggested that some people see Mars as more serious than he actually is. He said:

"People don't realise what a funny guy he is. He was always goofing around during the sessions."

As previously reported, Adam Lambert played at London's G-A-Y club on Saturday night (June 9), wowing fans with a set of new material.
