At her Las Vegas residency this weekend, Lady Gaga surprised everybody by bringing "A Star is Born" co-star Bradley Cooper on stage to perform 'Shallow'.
According to Uproxx, Cooper eluded to performing the song with Gaga at the Oscars in an interview last year.
?We talked about that actually, because I?m such a maniac. I started texting her the whole pitch of how we should do it. So we?ll see. There might be a cool, unorthodox way we could perform it.
