The reality Tv star marked her age milestone on Friday (27Jun14), but she celebrated the event a day early by partying with friends and family, including sisters Kourtney and Kim Kardashian and hip-hop mogul Sean 'Diddy' Combs and his girlfriend Cassie, at Don Coqui in her beau's native The Bronx, New York on Thursday (26Jun14).
During the night out, Montana presented the birthday girl with the keys to a white Jeep Sahara, reportedly worth $60,000 (£37,500), and handed her a $25,000 (£15,625) gold ring decorated with Colombian emeralds and yellow canary diamonds.
Earlier in the day, the Pop That hitmaker also gifted Kardashian with two mouth grills, which set him back an estimated $10,000 (£6,250), according to Tmz.com.
The couple became romantically linked four months ago, but has yet to officially confirm the status of its relationship.
The Keeping Up With the Kardashians star split from her estranged husband, basketball player Lamar Odom, last year (13), and she filed for divorce in December (13).
