Football star Reggie Bush is a new dad.  On Monday, his fiancee Lilit Avagyan gave birth to the couple's first child.

Bush, who famously dated Kim Kardashian, and his dancer girlfriend have been together for nearly 18 months. They announced the pregnancy news in October.

Bush, 28, is a Detroit Lions running back.

He and Kardashian had an on/again, off/again relationship for several years until they split in 2010. The reality star is seven months pregnant and expecting her first child with rapper boyfriend Kanye West this summer.
