Forget ooh-ing and ahh-ing over Prada and Jimmy Choo, girls these days can bond real super tight over something much furrier. Sienna Miller and Jessica Biel’s mutual love for their own dogs is making them quite the compatible duo.

The actresses are set to star together in the big screen adaptation of Oscar Wilde’s play A Woman Of No Importance alongside Sean Bean and sources claim that the two struck an instant rapport on the sets of the movie.

Jessica, famously linked to the animal charity PETA and the devoted owner to pitbulls, Tavy and Tina, talked continuously about her pooches, while Sienna gushed about her own pet dogs Porgy and Bess.

A Daily Express source was quoted as saying, “Jessica was telling Sienna about the animal charities she is involved with and asking whether Sienna wanted to get in touch with them.”
