Mariah Carey and Future Serenade Goldie Hawn On 71st Bday

Goldie Hawn got the first-ever Mariah Carey and Future duet on her 71st birthday when the two rolled up to her dinner table and gave an impromptu performance of "Happy Birthday."

It all went down Saturday at Catch, L.A.'s new hot spot. Goldie's daughter, Kate Hudson, threw the dinner for about 15 of Goldie's closest. Kurt Russell and their sons, Boston, Wyatt and Oliver, were also there.

Mariah happened to be at the restaurant too, as well as Future, who was there for DJ Khaled's book release party. We're told the two wandered over for a quick chat, but ended up singing "Happy Birthday" to Goldie together.

Also there that night ... Nicki Minaj, Meek Mill, Nas, Will.i.am, L.A. Reid and Ben Savage ... so, yeah, good luck getting a table.
