Hello, ‘SNL’ — Adele owes you big time for November appearance

Only four days after its debut, British singer Adele’s “Hello” single already has 76 million views on YouTube. Now “Saturday Night Live” plans to boost her visibility even more.

NBC announced Monday that she’ll be the musical guest with host Matthew McConaughey on Nov. 21 — a day after Adele’s new album, “25,” comes out.

Adele last sang on SNL in 2008, crooning “Chasing Pavements.” Oscar winner McConaughey last was on SNL in 2003.

The big debate on social media: Who will be the biggest star that night?

@Adele on #SNL I literally just screamed in class………
