But the romance didn't stop there. Wilde later took to Instagram to share a series of snaps from the evening.

"Best part of a great night," she captioned a photo of her and Sudeikis mid lip-lock.

She reiterated the sentiment in a close-up shot of herself -- which perfectly showed off the details of her makeup and accessories -- writing, "Such a f**king great night."

She also posted a pic of herself with Vinyl co-star Bobby Cannavale and executive producer Mick Jagger, captioning the snap, "Lucky lady."
