Taking to Instagram Stories, the blonde beauty finally introduced fans to her man.
Sharing a snap of the two, Monk wrote: "So lucky to have this guy in my life to help me recover."
In another photo, Sophie shared: "I've never been so happy."
While she is holding back on details on who her new man's identity, she certainly seems smitten.
Her spokesperson confirmed she was in a relationship, while Monk revealed she was dating a mystery man after the two met on an plane.
Back in August she told the Kyle and Jackie O Show they met on a flight from Italy.
“The lights were down, everyone else was asleep,” Monk said. “I went, ‘OK, shall we do this?’ And we kissed.”
