Ashanti, 43, surprised Nelly with his dream car at his Halloween/Birthday celebration in Fairburn, Georgia on Oct. 31. He turned 49 on Thursday, Nov. 2nd.

“He couldn’t believe Ashanti went out of her way to get him this vintage 1962 Impala,” the insider added. “He was in total shock and overcome with emotion when he saw it. This gift meant the world to him because it had a much more sentimental reason behind it. This was Nelly’s dream car since he was a kid and he couldn’t believe Ashanti gave him such a thoughtful gift. It’s one of the best presents he’s ever received.”

Nelly thanked Ashanti in an Instagram post on Friday. “Sometimes all you can say is ‘Thank You,’” he wrote alongside a photo of himself gangsta leanin’ in his new whip.

“Best gift I ever received besides my kids!!!! You showed out shawty!!! Love you @ashanti.”
