The Miami Dolphins star and his girlfriend Lilit Avagyan announced that they are expecting their first child together, People reports.
Meanwhile, Bush spoke about Avagyan's pregnancy on Florida radio's Paul and Young Ron Morning Show.
"We're pretty excited," he said. "We're bringing a new life into the world, and to raise a child is a gift for a man and woman."
Bush and Avagyan have been together for around a year, but Bush previously famously dated Kim Kardashian until they split in 2010.
Earlier this year, Bush was forced to deny rumours that he had reunited with Kardashian after her split from husband Kris Humphries.
