One day after the tragic death of Bachelor beauty Gia Allemand — who was taken off life support on Wednesday after a suicide attempt left her with brain and organ failure — Breaking Celebrity News has exclusively learned the 29-year-old brunette was upset that her NBA player boyfriend hadn't proposed to her yet.

According to sources close to Gia and Ryan Anderson, the usually happy couple got into their first blowout fight while in Las Vegas together at the end of July which had the former Bachelor Pad star worrying the relationship wasn't headed to the alter.

"Gia and Ryan were a happy couple. It's unfair to categorize their relationship as rocky, but in the weeks leading up to her death they did have their first major fight," the insider exclusively revealed to Breaking Celebrity News.

"And because their relationship was so solid for the most part, Gia had expressed her sadness that Ryan hadn't proposed to her yet, telling friends she was upset over it."

Gia and Ryan were in Las Vegas together three weeks ago appearing happy — the Bachelor star even posted the following photo on her Instagram account with the caption "#TheWynn #Vegas":
