Katy Perry has sparked rumours she is pregnant after being seen looking at baby clothes

Is she or isn’t she? The rumor mill is working at full speed. Can you say shotgun wedding?

The ‘I Kissed A Girl’ singer – who recently announced her engagement to British comic star Russell Brand – took a stroll around some children’s shops in Hampstead, London, on Sunday (10.01.10).

A source told The Sun newspaper: “Russell and Katy had a wander around Hampstead. They visited children’s shoe shop Cubs and had a lot of fun checking out all the little bootees.

“They then went to Cafe Rouge for a bit of lunch. Katy ordered scrambled eggs and asked for the eggs to be ‘well done’. And when Russell asked for a portion of chips she loudly announced to the waiter, ‘Hold the mayo’.”

Pregnant women are not allowed to eat freshly made mayonnaise because the recipe contains uncooked eggs, which are considered a health risk to unborn babies.

Katy, 25, has further fuelled the rumours by posting several cryptic messages on her twitter page.

In a posting on New Year’s Day (01.01.10), she said: “It’s noon on Jan 1st here in the future, let me tell you 2010 is BUMPIN! (sic)”

She then wrote to Russell: “I heard ur prego-ed.”

She then messaged gossip blogger Perez Hilton, saying: “Boy do I have storrrrries!(sic)”
