The level of fan engagement Monday indicates the duo will likely bolster the Fox show's digital chops -- which may be necessary considering Simon Cowell only joined Twitter last season.
Spears -- or at least her social media team -- tweeted a photo of herself with judges Cowell and L.A. Reid just moments before they went on stage with Lovato at Fox's programming upfront in New York City.
The surprisingly blurry photograph went up at 4:38 p.m. ET, accompanied by two hashtags that quickly trended worldwide on Twitter (see below). As of 6 p.m., the tweet has racked up 8,325 retweets.

Not long after, Spears turned to intimate social network Path to share the news, which she also pushed to Facebook via Path. The Facebook post attracted 11,000 Likes, 650 shares and 821 comments in an hour.
Spears's involvement with Path began in March when she visited the startup's San Francisco headquarters and published a post on the service.
Thanks for showing me Path Dave. I LOVE IT!!! Xoxo (with Dave at @path) — path.com/p/2b9yJG— Britney Spears (@britneyspears) March 15, 2012
Lovato, on the other hand, didn't rush the announcement, opting to tell her Twitter followers at 5:20 PM ET.
It's official! #SimonBritneyDemiLA#DemiXFactor. I am so excited!!!! twitter.com/ddlovato/statu…— demetria lovato (@ddlovato) May 14, 2012
X Factor last season became the first show ever to let viewers vote via Twitter's private direct-messaging system.
