AceShowbiz - It's been a while since Blu Cantrell was in the spotlight. The singer recently took the stage at The O2 in London, England for a performance, and immediately caught attention due to how different she looked compared to her appearance years before.

Performing several hits that included her collaboration with Sean Paul "Say You Love Me", Blu looked bigger than before as she covered her body in a floral-patterned gown and a black cardigan. She now sported a long, curly blonde hair and went with minimal makeup.

Footage of her performance that night soon hit the Internet, and people were having a hard time recognizing her. "This can't be the same woman who used to Hit Em Upstyle?!" one said. "When did she get so....ummm fleshy? I wonder if her weight gain affected her voice," one other wondered.

Someone were not sure whether she was pregnant or simply gained weight, "Is she pregnant or did she gain weight? I’m glad to see her still performing. I wish her well." Meanwhile, another person said, "Oops is that what happens when ya man wanna get buck wild and ya go up and hit em upstyle?"

There was also one person who said, "She clearly still has a long way to go with her mental recovery though," probably referring to all the ups and downs Blu had in her career before she stepped out from the limelight.

Back in 2014, Blu was taken into police custody for a psychological evaluation after she went "berserk" and hysterically claimed that someone had poisoned her with gas.
