Karrueche Tran -- Death Threats Over Sexy Shot

A photo of Karreuche Tran has R&B singer Marques Houston looking over his shoulder after a comment he posted triggered death threats from a member of Chris Brown's crew.

Houston ogled Tran's pic, then paid her the highest compliment:

Houston's accolade set off one of Breezy's crew members, who responded by posting a pic of semi-automatics and a jarring warning.

The warning cannot be taken lightly, because the crew member is a known gang member.

You may recall, back in May, Tyson Beckford posted a pic of himself with Karrueche and Chris responded by tweeting, "U wanna keep walking them runways. I need ta legs for that."
