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 RadarOnline.com: ''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.
