15-time Grammy winner Adele showed off her American accent in the first for her hosting debut on this week's Saturday Night Live.

The London-born 32-year-old demonstrated her dialect after SNL castmember Kate McKinnon attempted a dodgy English accent: 'So tune in! It's fit to be wicked. I'm sorry! Bad idea. That was pathetic.'

Adele - rocking a purple crushed-velvet blouse - replied: 'Oh my god! No worries, girlfriend!'

The 36-year-old Long Island native was impressed: 'Okay, now that is good!'

In the second promo - Adele, Kate, and first-time musical guest H.E.R. debated over which 'her' the Hiding My Heart singer was actually referring to during the introduction.

Fans expecting to hear the elusive torch singer's three-octave mezzo-soprano pipes on the NBC sketch show might have to settle for the 23-year-old Bay Area native (born Gabriella Wilson) singing her new single Damage.

H.E.R. - who scored two Grammy Awards for her R&B stylings - later gushed via https://www.instagram.com/p/CGqpEEWH61N/: 'Can't believe I'm gonna be on Saturday Night Live!'

'I am besides myself that H.E.R will be the musical guest!' Adele previously wrote on https://www.instagram.com/p/CGfpHYogAPE/ last Sunday.

'I love her SO much. I can't wait to melt into a flaming hot mess when she performs, then confuse myself while I laugh my arse off in between it all.'

The Oscar-winning songwriter admitted she's 'so excited' but 'also absolutely terrified' to finally host SNL. 

'I've always wanted to do it as a stand alone moment, so that I could roll up my sleeves and fully throw myself into it,' Adele - who boasts 151M social media followers - wrote Sunday.
