E! reality star Christina Milian and Young Money rapper Lil Wayne appear to have gone public with their romance after being pictured holding hands while out in Hollywood.

The Start A Fire collaborators were seen strolling around a film set in Los Angeles on 25 March looking particularly happy with each other. AM to PM singer Milian could barely keep the smile off her face as Wayne, 33, engaged her in conversation.

The PDA comes just days after the 29-year-old songstress gushed over the Lollipop rapper in an interview with Latina magazine, describing him as her "man crush".

"I think he's awesome. He and I have a very special relationship and I think I've always been very careful with it publicly because when you have something special it's like everybody picks apart words. They'll pick apart a moment in a picture and take something that's special and trash it," Milian told the magazine.

Adding fuel to the speculation, Milian recently declared her love for a mystery person in a cryptic video posted on Instagram, saying: "This is for my bae, he knows who he is. I'm in love with you! You're the best thing ever, ever, ever in the whole world."

The musicians were first linked in July 2014 shortly after Milian ended her engagement to music producer Jas Prince. That summer, the singer and hip hop star were spotted on several 'dates' around LA and were seen holding hands at the ESPY Awards on 16 July 2014.

Whispers circulated again in November 2014 after the pair gave a sizzling performance at the American Music Awards.

Some have raised eyebrows over their rumoured romance due to their complicated family tree – Milian has a daughter with music producer The-Dream, who also has a daughter and twin sons with r'n'b singer Nivea. Nivea in turn has a son with Lil Wayne.
