Katy Perry thinks boys are just as excited about seeing her 2011 tour as girls.

The 'Firework' singer knows she has more female fans than male admirers but is confident any guy who is being taken to one of her concerts by their girlfriends this year will enjoy her show.

She said: "That's the thing with me, I think a lot of girls are bringing their boyfriends along, but the boyfriends aren't dragging their feet. They will be secretly excited to be coming to see me, I think."

Katy - who is married to Russell Brand - is also confident she may be able to convince a special guest to put in an appearance at some concerts if their schedules allow for it.

She added: "Perhaps Snoop Dogg will make a surprise guest appearance if he happens to be in the same city at the same time. The boyfriends would enjoy that!"

Snoop guest starred on Katy's single 'California Gurls'. Her European tour starts in Lisbon, Portugal, on February 20 and runs until April.
