This Morning fans were gobsmacked after Alison Hammond's gesture to Janet Jackson on today's show.
The popular presenter was fronting Tuesday's edition of ITV's flagship daytime programme as Phillip Schofield continues to self-isolate after contracting coronavirus.
Alison interviewed legendary singer Janet Jackson via video call ahead of a new four-part documentary series which lifts the lid on the US star's glittering career.

The 47-year-old host donned her best Janet-inspired attire for the occasion, with black leather gloves and an earring with a key hanging from it.
Janet is renowned for her dancing ability and she taught the presenter how to do the iconic hand movements from her song Rhythm Nation.
The routine counts down from five fingers - and Janet was in hysterics when Alison got confused and left her middle finger up.
A mortified Alison apologised, but Janet insisted "no offence" was taken.
She added: "When you first learn it, that happens all the time, I did that so much."
Viewers following the show on Twitter were in stitches after the gesture.

@MrEvilSkeletor added: "She just flipped Janet Jackson off!""
Patrick posted : "Alison Hammond just flipped off Janet Jackson and I’m roaring"
