It's one thing to tackle a superstar diva's song on a TV talent show, but it's quite another to take on a song by two of the biggest singing stars of the last century. That's exactly what mother and daughter Ana and Fia did performing Barbra Streisand's and Celine Dion's soaring "Tell Him" on "Britain's Got Talent." From the judges' reaction, the risk paid off for the duo.
The emotional song of one woman giving another advice to embrace finding love elevated the fact that a mother and daughter performed it together. Cameras caught judge Amanda Holden clearly tearing up during the performance, as even judge Simon Cowell couldn't help smiling at the emotional - and vocally beautiful – performance. 

"There's nobody else in the race to be the next Barbra Streisand," producer David Foster remembers thinking of Dion during the duet's original pairing, as captured in the video of the making of the superstar duet. Although both singers famously recorded multiple hits before the duet, Dion saw it as an opportunity to record with her musical idol.  The song was nominated for a Grammy for Best Pop Collaboration with Vocals in 1998, but according to Total Music Awards, lost the honor to the song "Don't Look Back," performed by John Lee Hooker and Van Morrison.

The clear admiration between Streisand and Dion may not even be enough to match the unique chemistry between this mother and daughter who obviously felt emotional performing together.

Do you think this amazing performance by not one but two incredible singers might be a "Britain's Got Talent" moment people will talk about for years? Make sure and share it with your friends ... but warn them to grab a tissue first!
