Just when we thought things couldn't get any worse over on The Real Housewives of Beverly Hills.
But that wasn't the case!
So the rumors ARE true…
At least partially!
Instead, the former singing competition judge will grace the American Idol stage to PERFORM during the show's two-part finale!
No news yet as to which night the Dance, Again mover and shaker will dazzle audiences with her sexy self OR what tune she'll sing…
Although wouldn't Jen's performance be a subtle slap-in-the-face to Mariah who ALSO has a new single coming out next week?
What a major case of stolen thunder!
