The singer has never been shy about showing some skin in her stage outfits but is now taking a more confident approach to her day-to-day dressing.
Gaga put her wacky outfits to the back of her wardrobe and replaced them with two very slinky ensembles on Wednesday.
The 27-year-old is currently holidaying in East Hampton and appears to be making the most of the shops on offer in the New York town.
Gaga was spotted in a very sexy black pencil dress with a zip all the way down the back as she stepped out in the sunshine.
While the white outfit was just as sexy as the black number, the only things that remained the same were Gaga's black handbag and angular sunglasses.
As well as stocking up on clothes for her new slimmer frame, the pop star was also seen getting her caffeine fix as she picked up a double espresso.
Gaga was recently in Cabo San Lucas, Mexico, where she acted as a bridesmaid at a friend's wedding.
The source added: 'Taylor has the perfect excuse for going for days out with Cameron as they're workmates, but they're not just being close at work.
'Cameron and Taylor have been seen in cafes and went out for dinner. They were joined at the hip at a drinks party for Kate Upton's birthday.
'She has also met Taylor's family as his brothers Adam and Trent have visited the set.'
