Solange Knowles was still in the throes of wedded bliss a day after her wedding to Alan Ferguson.

Beyonce's baby sis posted a snap of a tender moment she shared with Ferguson after the couple exchanged vows Sunday in New Orleans.

"Yesterday, I had the best day of my life and ended it with an abundance of peace, love over flowing through me like never before," she wrote on Instagram Monday. "Words only understate the feelings I experienced , but I want to thank you for all of your beautiful sentiments. I'm now one, with the one."
