After just one episode, 'Precious' star Paula Patton has bowed out of her new role as an ADA on 'Law & Order: SVU.' The reason? She'll be in 'Mission Impossible 4.'

Melissa Sagemiller of TNT's 'Raising the Bar' will replace Patton on the hit NBC series. Patton was tapped to play ADA Mikka Von on a recurring basis, but now she'll appear in one episode before Sagemiller takes on the recurring ADA role in October.

According to TV Guide, Sagemiller will be an ADA from Brooklyn who respects Stabler and Benson.

Natalia Cigliuti has joined the cast of Raising the Bar, a new legal drama from TNT. She will play public defender Roberta "Bobbi" Gilardi. Joining Cigliutti are Mark Paul Gosselaar (NYPD Blue), Gloria Reuben (ER), Jane Kaczmarek (Malcolm in the Middle), Teddy Sears (Ugly Betty), Melissa Sagemiller (Sleeper Cell), Currie Graham (Boston Legal), J. August Richards (Conviction) and Jonathan Scarfe (Into the West).

Cigliuti will co-star with Gosselaar. Her character Bobbi, a Brooklyn native, is brought in to help with the strenuous workload at the public defender's office. Gosselaar flirtatiously calls her "Bobbi from Brooklyn" and takes an interest in his new co-worker.
