Lady Gaga and Celine Dion have been added to a Grammy tribute to Frank Sinatra. The ladies will join Zac Brown and Harry Connick, Jr among other stars, at the Sinatra 100 - An All-Star Grammy Concert to be held at the Wynn Las Vegas on 2 December.

The tribute, which will also feature Sinatra's protege Tony Bennett, Adam Levine and Alicia Keys, will air in America four days later (06Dec15). Thrilled to be part of the show, Celine Dion says, "I've been singing Frank Sinatra songs in my shows for many years. His voice has been such an inspiration for me and it will always be."

"My grandfather introduced me to Frank Sinatra," Keys adds. "I love hearing his songs, the phrasing, the innocence - the subtle depth that knocks you out when you concentrate on the lyrics. And those arrangements! It brings me back to the lost art of 'the gentleman'." She plays the murderous and blood-thirsty The Countess on the latest season of Ryan Murphy's American Horror Story. However, Lady Gaga seemed to be enjoying a tender moment as the dangerous character on Tuesday, as she was spotted filming in Hollywood with co-star Finn Wittrock.

The 29-year-old was seen sharing a kiss with the 31-year-old actor as the pair exited a hotel room together. In typical The Countess fashion, Lady Gaga looked chic for the scenes, in a fitted, grey jacket which fell to her ankles.

The thick coat featured wide lapels and a large belt that cinched in at the performer's waist, accentuating her slim figure. Lady Gaga coupled the look with a pair of tan, leather gloves, finishing it off with classic, black pumps.
