Bobbi Kristina Brown's beau, Nick Gordon, is showing off his love of guns while driving.

The 22-year-old, who has been dating Whitney Houston's daughter, posted the above photo, but then quickly removed it. After taking down the pic, Nick Tweeted:

    "I apologize for posting a picture with my registered gun. That's not what we stand for and I didn't mean harm by it, it's a collectors item. Moving forward I'll obviously be more mindful/thoughtful about how my actions influence others and reflect on the ppl I love and care about."

The 19-year-old daughter of Bobby Brown recently Tweeted, "I & @nickgordon loveUall! Ha thank4ur love & support! We R both collectors of guns actually, We always have been. Lol.''

Bobbi Kristina and Nick are currently filming the reality show The Houstons: On Our Own ... due to premiere next month.
