Rapper Young Jeezy has introduced his baby girl to the world, a year after secretly becoming a father for the second time.

The Put On hitmaker, real name Jay Jenkins, celebrated the tot's first birthday last Thursday (05Feb15) by sharing a photo of himself cradling his daughter on Instagram.com.

In the accompanying caption, the 37-year-old star wrote, "Since the 1st day you were born, I've been a better man, individual and father. You are my light, my motivation and my inspiration. Happy Born Day my Angel."

Jeezy has yet to reveal the girl's name or identify the baby's mother.

The one year old is the half-sister of the rapper's 18-year-old son Jadarius Jenkins, his son with ex-girlfriend Tenesha Dykes.
