He stood about 5 feet tall, religiously rocked cornrows and was the lead singer of the now defunct, B2K. Can you guess who?

If ‘Post To Be’ singer Omarion came to mind, then you’ve got it!

On Instagram Thursday, Solange posted a picture of her and Omarion along with Destiny’s Child and B2K band members at a birthday party. Underneath the photo, the now happily married singer wrote, "Am I trolling, or nah? #tbt to when me and @1omarion were lil teenage boo's, but used to have hide it because I was scared dem b2k fans would try to cut me, lol.”

Long time fans of Solange and Destiny’s Child know that the girls have always been tight-lipped about their personal lives. So it’s no wonder this teenage love affair went unknown for so long.

The two have since moved on -- Solange tied the knot to video director Alan Ferguson in a stunning New Orleans wedding last year. And more recently, Omarion, who is starring in his second season of ‘Love and Hip Hollywood’, announced he is expecting baby number two with girlfriend Apryl Jones.

As for the #TBT photo, it has since been removed.
