Sara Gilbert, Allison Adler Split

Sara Gilbert, cohost of The Talk and costar on Roseanne and other TV series, and producer-writer Allison Adler have ended their 10-year relationship.

"It's completely amicable," a representative for Gilbert told Peoplemagazine. Gilbert, 36, and Adler, 44, will share custody of their children -- son Levi, 6 1/2, and daughter Sawyer, 4.

Gilbert first gained fame as daughter Darlene Conner on Roseanne and has also appeared on such series as ER, 24, and The Big Bang Theory, and movies including Poison Ivy. She launched the daytime chatfest The Talk last year. Adler's credits include No Ordinary Family, Chuck, Veronica's Closet, Just Shoot Me! and Family Guy.
