Carrie Underwood Joins Tony Bennett for ‘Blue Bloods’ Season Premiere

Carrie Underwood looked elegant as she crooned alongside Tony Bennett during Friday night's episode of 'Blue Bloods' on CBS. The two played themselves on the Tom Selleck/Donnie Wahlberg drama, and sang 'It Had to Be You,' the song they recorded together for Bennett's new 'Duets II' album.

Bennett's appearance was cleverly worked into the plot of the season opening episode. Frank Reagan (played by Selleck) and his daughter Erin (played by Bridget Moynahan) attend a black-tie fundraiser thrown by the new Mayor-elect. The older Reagan hints that the only reason he's going is because Bennett is performing, and it turns out the singer and cantankerous police commissioner are old pals.

After singing with Underwood, Bennett calls Reagan out by name and asks him to throw out a speeding ticket. The audience and lead characters chuckle at the 85-year-old's joke. Underwood's role was minimal. Aside from singing, her only line was to remind people that her duet partner's album was in stores. To her credit the line didn't feel as much like a commercial as it did just another line of dialogue.
