WATCH: Bradley Cooper joins Lady Gaga on stage in Vegas for live performance of ‘Shallow’

What we would've given to be there for this!

For anyone who still doesn't think that A Star Is Born is a landmark moment in modern cinema, it might be time to take stock. On top of the fact that the soundtrack is one of the biggest selling albums of 2018, it has recently been nominated for no less than EIGHT Oscars, including Best Actor, Best Actress, Best Screenplay, Best Picture, and (of course) Best Song. To date it has made over $400 million at the box office, which is more than blockbusters like Solo, Fifty Shades Freed, The Nun, or A Quiet Place. Even with all of the awards shows taking place right now, Lady Gaga is still going strong with her Enigma residency in Las Vegas, and this weekend patrons were gifted with the arrival of none other than Bradley Cooper himself, who broke ranks from the audience to join Gaga on stage for a duet rendition of their Oscar nominated song 'Shallow'. To say that the fans present promptly lost their minds is a bit of an understatement: https://twitter.com/phuckdemon/status/1089419213096157184 https://twitter.com/danielun/status/1089419462535593984 https://twitter.com/JennMGMPR/status/1089423470608314368 https://twitter.com/chigurrlk/status/1089434161201344513 https://twitter.com/KevinMcCarthyTV/status/1089407112302608384 In case you missed it at the time, we were lucky enough to sit down with Cooper to chat about A Star Is Born, his love for Gaga, and the Scorsese influence on the movie's most romantic scene:
