Justin Timberlake stopped mid-show in Detroit on Monday to announce a pregnancy.

He noticed a sign in the massive crowd at Little Caesars Arena during his show, and helped a fan make a huge announcement.

The fan was Darcell Baxtresser, and she was holding a huge sign that said, "Will you help me announce my pregnancy? Due November 1st, 2018."

JT asked if the dad was with her, and Darcell said no. Timberlake offered up a possible name of Baby Bax, and the crowd went nuts. Darcell caught the entire moment on video and posted it to FB with the comment,

This was the most amazing, magical, unforgettable moment I have ever had in my life!!! My first love to announce my pregnancy was crazy!!! A truly special memory I will forever cherish!! Thank you!! ❤️Justin TimberlakeThe Tennessee Kids #BabyBax #BestPregnancyAnnouncementEver #NoOneCanTopThat #JTisTheBest #MOTW #JustinTimberlake #ILoveHim #WorthEveryPenny
