Mariah Carey liked the band on a recent dinner date in New York so much that she took them home to keep entertaining her.
The 41-year-old diva - who became a mother to twins in April - was dining out with husband Nick Cannon at Tolani, the supper club at TriBeCa's Theatre Bar, where classical guitarist Nilko Andreas was performing with his group.
Mariah and Nick liked the Colombian-born musician's playing to much they went backstage afterwards and invited him back to their house, The New York Post reports.
Nilko apparently agreed and joined them at their downtown loft apartment for a private jamming session.
America's Got Talent host Nick turned 31 last week.
He tweeted: "My wife my mom and my kids made it the most amazing day ever" and posted a picture of himself celebrating with his family.
