Ooopss, they did it again! Alex Jones has become the latest BBC presenter to have a Basic Instinct moment after flashing her knickers live on air.

The One Show presenter, who was wearing a tight- fitting fuchsia shift dress, was left red-faced when she gave viewers an eyeful while presenting the programme alongside co-host Matt Baker.

The embarrassing gaffe occurred when she went to cross her legs as the duo asked grooms to send in images of their wild stag nights.

Eagle-eyed viewers quickly took to social media to share their reactions.

"I couldn't resist it. Alex Jones of the #OneShow flashes 'er Knickers live on tv. Black with polka dots," one amused commentator said.

Another wrote: "Anyone else clock Alex Jones flashing her knickers on The One Show tonight whilst sorting her dress out?? #oops"

In December 2013, BBC Breakfast host Susanna Reid gave viewers a different type of wake-up call when she flashed her knickers while presenting the morning papers.

The Beeb has not commented on the latest slip.
