Mumbai, Aug 11 : Reality television star Kim Kardashian is celebrating her sister Kylie Jenner's birthday and extended a heartwarming message.

On Sunday, the actress took to her Instagram, and shared a series of pictures of herself with her sisters. The carousel also includes many throwback pictures from their teens.

Kim Kardashian wrote in the caption: 'I want to thank the universe for blessing me with a sister as sweet as you. Your silliness, kindness and love are the greatest gifts I could ever ask for. Happy Birthday, with all my heart you private little soul you @kyliejenner You're basically 30 now.'

Kim, who is the founder of the garment company Skims, has an older sister, Kourtney, a younger sister, Khloe, and a younger brother, Rob. Their mother Kris Jenner took divorce from their father Robert Kardashian in 1991, and married Bruce Jenner, a former Olympic gold medal-winning decathlete.

As a result of her mother's remarriage, Kim Kardashian acquired step-brothers Burt, Brandon, and Brody; stepsister Casey; and, later, two half-sisters, Kendall and Kylie Jenner.

Kris Jenner and Bruce separated in June 2013 citing irreconcilable differences. Their divorce terms were finalised in December 2014 and went into effect on March 23, 2015. Bruce later came out as a transwoman in 2015.

Kim started her career in 2003 as a personal stylist to the R&B singer and actress, Brandy, the sister of Ray J. However, she got into a tiff with the mother of Ray J and Brandy who alleged that the reality star had made unauthorised purchases on her credit card. These unauthorised purchases were attributed to a boutique owned by the Kardashian family.

Later, Kim Kardashian became a personal stylist to her childhood friend, Paris Hilton. She appeared in several episodes of the reality series 'The Simple Life' and was frequently photographed accompanying Hilton to events and parties.
