Britney's dogfight with Paris

The unkind would call it the battle of the bitches - referring to the dogs, of course.

Britney Spears and Paris Hilton are now exchanging claw marks not over their fame, beauty or money - but about their pet chihuahuas.

Singer Britney says the hotel heiress's pet Tinkerbell looks like a dog's breakfast. Her own three pooches - Bit Bit, Lacy Loo and Lucky - are far better turned out, she claims.

'My dogs are stylin' and profilin',' the Toxic singer wrote on her website.

'Von Dutch just sent them the coolest little clothes. My dogs are so much cuter than Tinkerbell (ruff! ruff!).' The celebrities, both 23, are rarely seen without their pedigree chums.

And the dogs have been snapped in a variety of designer gear. Bit Bit wore a lavish diamond-studded collar to the Billboard Music Awards in December.

Tinkerbell and Ms Hilton, meanwhile, sported matching outfits on reality TV show, The Simple Life. The dog even inspired this month's Paris Hilton jewellery collection. 'A lot of people admire Tinkerbell's look,' she said. 'So I included a glamorous pet collar.'
