Lively, 27, who recently gave birth to the couple's first child, took to Instagram to (jokingly) confront her flirtatious husband.
"Should I be concerned that my husband's never looked at me this way?... #WhereAreThoseEyesWanderingReynolds #HelenMirrenIStheSexiestWomanAlive #WomanInGold," the "Age of Adaline" star captioned a pic of Reynolds and Mirren on the red carpet.
In the pic, Reynolds and Mirren are arm and arm, with the actor's eyes apparently drifting down to the veteran actress' decolletage.
