Yesterday (9 October), Hayden appeared on US show Live With Kelly & Michael and revealed that Wladimir had recently proposed to her.
Pictures of Hayden arriving at the TV studios for the interview have now emerged - and she's seriously flashing one huge rock!
Posing outside, Hayden coordinated her engagement ring with black skinny trousers, a monochrome jacket and a striking pair of red leather ankle boots.
She kept her blonde hair straight in a centre parting and completed her look with natural make-up and plum coloured nails.
The actress, 24, has been dating 37-year-old Wladimir since August 2009. They briefly split two years later but rekindled their romance earlier this year.
Rumours of an engagement first began circulating in August after Hayden was spotted out and about with this ring on her wedding finger.
