Awkward news for Kim Kardashian -- her ex-boyfriend Reggie Bush just announced his current GF Lilit Avagyan is pregnant with his first child ... and it BETTER not be a girl ... or else.

Reggie called in to the Paul and Young Ron Morning Show to make the announcement -- saying, "I have a little one on the way. We're pretty excited ... It's an opportunity to bring in new life and raise a child."

Reggie added, "I'm hoping for a boy because if it's a girl, I'm going straight to the gun shop to buy some guns."

Reggie was presumably joking that he would need guns to protect his daughter.
