While Katy Perry was recovering from a bout of food poisoning, her husband Russell Brand was photographed enjoying a lazy poolside afternoon with a mystery brunette, who at a glance resembles the Teenage Dream singer.

Even if the woman is just a friend (it is possible that she is his longtime stylist), Brand could still be in the doghouse, as he and Katy made an agreement never to be photographed with a member of the opposite sex.

The couple has been battling rumors that their marriage is on the rocks, and a photograph of them together on Sunday came at a time when public sightings of Perry and Brand together have become increasingly rare.

Perry canceled two of her scheduled concerts over the weekend, citing severe dehydration from a bout of food poisoning.

Brand, who is best known in the United States for his role in Forgetting Sarah Marshall and Get Him to the Greek, was previously well-known in England and had developed a reputation as a notorious ladies' man. He was awarded The Sun's Shagger of the Year award three years in a row, leading the newspaper to rename the award The Russell Brand Shagger of the Year Award in his honor.

Brand is open about his former life as an addict to sex, drugs, and alcohol, and has stayed clean since 2002.

Aldous Snow, his character in Forgetting Sarah Marshall and Get Him to the Greek, is a self-mocking reference to Brand's extreme living.

In a 2011 interview with Piers Morgan, Brand expressed some amibvalence about remaining faithful for the rest of his days. I take it one step at a time - like with drugs, like with alcohol, he said. Don't look at things as in 'rest of life'.
