In a recent performance, legendary Canadian singer Celine Dion paid tribute to the late Bee Gees brothers with a rendition of the song "immortality" - a song they composed for her 20 years ago - all while rocking a flawless Elie Saab gown. 

"A spectacular performance by Celine Dion in ELIE SAAB Haute Couture at the Grammy Salute of the Music of the Bee Gees in Los Angeles," Elie Saab tweeted.

The performance dubbed Stayin' Alive: A Grammy Salute To The Music Of The Bee Gees was part of a Grammy-organized concert honoring the late Gibb brothers - Robin, Maurice and Andy Gibb. 

Dion dedicated her performance to the Gibb brothers, and to the only surviving band member Barry Gibb ... as well as her late husband and brother.

"I sing it with love for Barry, and in memory of Robin, Maurice, and Andy, as well as for my beloved brother, Daniel, and my husband, René," Dion said. 

It was a blue moment ... and Dion chose just the right color

The concert took place in Los Angeles in February, but was aired earlier this week.

Dion was one of many artists who came together to honor the late Australian pop music group, including John Travolta, and Demi Lovato among others.

It's definitely not the first time Dion chooses to wear Saab!

It seems as though she really loves Saab's designs ...

Like really, really loves his gowns

Yup, Saab is definitely her favorite.
