The artists won awards Saturday during the 2-day Creative Arts Emmys ceremony in Los Angeles. Adele's 'One Night Only' show -- where she was singing at the Griffith Observatory last year -- took home five Emmys, in fact ... including for Outstanding Variety Special.

As for Em ... he too won for Outstanding Variety Special, although his was for the live version (Adele's was pre-recorded). As we reported ... him, Dre and the rest of the SB gang are all Emmy winners now for their Halftime Show performance earlier this year.

With Shady, that means he's just a T away from EGOT. His longtime manager, Paul Rosenberg, noted that on Twitter.

Just for a refresher -- Eminem has won an Oscar for Best Original Song in "Lose Yourself" ('8 Mile), tons of Grammys, and now ... an Emmy for his Super Bowl gig. Adele has also won an Oscar for Best Original Song in "Skyfall," Grammys galore, and now this as well.

The Tony is by far the hardest award to win for entertainers who don't normally do theater work (like these two) ... but there's ways to earn one without having to necessarily perform.

They could each write songs for Broadway shows and win that way, or contribute to the musical arrangement of an original song -- which is well within their wheelhouse. Both could easily do something like that and potentially win a Tony, assuming they're interested.

If they each won EGOTs, they'd join a relatively small and prestigious list of past winners -- including Whoopi Goldberg, John Legend, Rita Moreno, Mel Brooks and a handful of others.

For now, though, they're on the list of 4-award winners, sharing company with Liza Minnelli, Barbra Streisand, James Earl Jones, Quincy Jones and Harry Belafonte.

Not a bad crowd!
