Lindsay and Ali Lohan are poised to follow Britney and Jamie Lynn Spears' tough sister act.

Ali, 12, is in talks with Disney to clinch a deal to star in her own show. And big sis Lindsay, 19, is thrilled. Ali saw the great success Jamie Lynn, 14, had on her show Zoe 101 and has a similar plan.

Ali — who will be managed by her mom Dina — recently starred in Lindsay's music video Confessions Of A Broken Heart, based on their stormy relationship with 44-year-old father Michael.

Ali plays Lindsay in the video and is seen tearing her hair out as her father punches her mother. Lindsay, who also began her career when she was 12, recently said of Ali's performance: "I cried when I saw it. It is like therapy in a way."
