Mariah Carey stole Meryl Streep's seat at the Golden Globe awards on Sunday (07.01.18).

The 47-year-old singer had to scramble to find somewhere to sit after heading out to the bathroom during a commercial break and spending so much time ''mingling'' at the Beverly Hilton hotel in Beverly Hills, she couldn't make it back to her own spot in time so had to perch wherever she could.

Finding a chair next to 'The Post' director Steven Spielberg was vacant, Mariah slid in - but was horrified when she realised her error.

She revealed on Twitter: ''Got caught mingling on the way to the loo during a commercial break.. took the first seat available, happens to be right next to Steven Spielberg.

''Cut to next commercial break, guess who comes back to her seat...(sic)''

Fortunately for the 'Fantasy' singer, the Best Actress in a Motion Picture, Drama nominee wasn't particularly upset.

Mariah continued: ''(me) Dear Meryl, please forgive me!!!

(MERYL STREEP) You can take my seat any time! (sic)''

The 'One Sweet Day' hitmaker was at the ceremony because she'd been nominated for Best Original Song for 'The Star', which she co-wrote with Marc Shaiman and performed in the animated movie of the same name, but she wasn't too upset to miss out on the prize, which went to Pasek & Paul for 'This Is Me', which features in 'The Greatest Showman'.

She tweeted: ''Congratulations ''This Is Me''! A beautifully written song and very deserving. Marc & I will try another year! (sic)''

And a highlight of the evening for Mariah was seeing Oprah Winfrey become the first black woman to pick up the Cecil B. DeMille Lifetime Achievement honour.

She posted: ''Congratulations @Oprah! You are an incredible role model. Thank you for your inspiring and moving words and for everything you have done for me personally. You have changed my life.(sic)''
