The 28-year-old actress took to Twitter to confess her love for her 37-year-old beau while watching the funnyman's performance on SNL.
"Nothing puts a smile on my face like the love of my life dancing in a track suit and curly wig," she tweeted Saturday afternoon.
Sudeikis appeared on the hit comedy show in the "What Up With That" skit, where he rocked out in a red tracksuit and curly wig as he did the Running Man for the amused audience.
Although the pair of one year recently moved in together, the Tron star took to Twitter last week to shoot down engagement rumors.
"No I'm not engaged," she tweeted, in an attempt to set the record straight: "But I AM at the Stones show and holy s--t Ronnie Wood you got style, boy. It's just a fact. Trying to score a shoe pic."
