Did Karrueche Tran Ignore Chris Brown At A Coachella Party?

"Chris has become very insecure now that Karrueche left him. He doesn't feel like the big man on campus anymore," the source revealed.

"He doesn't feel confident to pick up women anymore. His love for Karrueche has knocked the wind out of him and humbled him at the same time," the source further explained.

"He's really lost without her," the source added.

Brown apparently has a grand gesture planned for the model's upcoming 27th birthday (May 17) regardless of her ignoring him.

The entertainment site revealed on Tuesday night that Brown plans to propose to Tran!

"Chris doesn't want to lose this girl. She's by far the most impressive woman he's had a relationship with in his entire life. He's been watching, and re-watching her interview [on OWN] and one thing keeps on sticking out to him: her wiggling her ring finger and saying she'd marry him," a source shared.

"He wants to step it up and show her he's serious about her, their relationship. He may just pop the question to her on her birthday to show her that he's a man of his words and that he's ready," the source added.

Do you think Brown will propose to her?
