The 'Loyal' hitmaker and Karrueche Tran called time on their relationship earlier this year after it was revealed Chris had fathered a daughter, Royalty, with Nia Guzman-Amey, but the singer is now reportedly hoping the pair can rekindle their romance.

A source said: "Chris has been blowing Karrueche's phone up, calling and texting her.

"He's dying to see her in Vegas and has been pleading with her to make his birthday wish come true. All he wants to do is see her."

Meanwhile, the 26-year-old model is believed to be pleased her former flame is "growing up" since finding out he has a child.

Another insider told HollywoodLife.com previously: "When Karrueche saw the photo of Chris and Royalty, she dropped her phone. She went to the bathroom for a few minutes to catch her breath and compose herself, and when she came back out and looked at it again, she smiled. The fact that Chris is finally growing up makes her happy.

"Karrueche is so proud of Chris and finds it refreshing that he's taking care of his responsibilities. She's so happy Royalty has her father in her life. It's something she wishes she wish she had when she was Royalty's age."
