No need to add any sweetener to this soirée—it looks like Ariana Grande's 25th birthday celebration was her sweetest yet.
Donning a Louis Vuitton-themed ensemble with a coordinating skirt, purse and kitten ears paired with knee-high boots, the songstress and her beau headed to the Mandarin Oriental in New York City for a celebratory dinner. According to a source, the couple was joined by a bunch of friends as they made their way to the hotel.
"She looked really happy," the source described. "[Ariana and Pete] held hands as they got into the car."
