Britney Spears and her boyfriend went shopping for a new puppy this week.

The 'Perfume' hitmaker, who has been dating David Lucado since last March, ''fell in love with'' a $5,000 teacup Yorkie named Micro Diamond at Star Yorkie in the San Fernando Valley area of Los Angeles on Thursday afternoon (09.01.14).

The pet shop's owner told ''Britney and David were friendly. She was in a great mood and seemed happy playing with the puppies.''

The 32-year-old star and David, who works at a prestigious law firm in Southern California, spent 30 minutes playing with the pooch, who is described as ''an absolutely gorgeous puppy with a personality that is a lot larger then her size'' on the shop's website, but they decided to think about it at home before making a decision about the dog.

The owner said: ''They left empty-handed, but I wouldn't be surprised if they come back for Diamond.''

Britney, who has sons, Sean, eight, and Jayden, seven, with her ex-husband Kevin Federline, is a well-known animal lover and has adopted a Yorkie and a Maltese from the same pet shop in the past.
