The American Idol alum and boyfriend Jimmy R.O. Smith got engaged over the New Year's holiday, PEOPLE confirms.
Toscano, 27, was a contestant on the tenth season of Fox's singing competition in 2011, and has since appeared in Burlesque and Dreamgirls. Currently, the star is a background vocalist in Jennifer Lopez's Las Vegas residency "All I Have" at Planet Hollywood.
"Pia and Jimmy met last year on J. Lo's tour," a source confirms to PEOPLE. "She was singing backup and he is J. Lo's backup dancer."
The couple toasted 2016 with a joyous selfie photo, which showed off the diamond engagement ring Toscano's fiancé gifted her.
"The #NewYear countdown with my future Mrs. SMITH. A toast to topping every year we've all ever lived. G.i.g ---#ourlastnewyearcelebrationsingle #MrandMrsSMITH," he wrote.
Coincidentally, Toscano's ex Mark Ballas recently got engaged to his girlfriend B.C. Jean.
