The leggy blonde was all set to join boyfriend George for the star-studded White House Correspondents' Dinner and even Tweeted about having her dress fitted just a few days before.
But last minute work plans left George without a date for the prestigious event.
'She couldn't make it. She's working," George told Politico before proudly explaining that his girlfriend just landed a pilot for a TV show.
Keibler took to her Twitter page Sunday morning to tease her fans about the show.
"Long first day shooting on my new project yesterday," she wrote. "But time flies when you are having fun! Can't wait to see what today brings!"
Keibler has just landed a guest spot on the new show Men At Work which she shot earlier in the week.
