Lively took to Instagram on Friday to tease her husband about a red carpet photo of him and the 69-year-old Oscar winner staring lovingly into each other's eyes.
"Should I be concerned that my husband's never looked at me this way?... #WhereAreThoseEyesWanderingReynolds" Lively joking captioned the well-timed photo.
To her credit, Lively also tagged the pic with the most accurate hashtag ever: #HelenMirrenIStheSexiestWomanAlive
The photo was taken in February at the 65th Berlinale International Film Festival in Berlin, Germany before a screening of Woman in Gold, in which Reynolds and Mirren co-star.
