Germany's Next Topmodel
After applying to an open casting call in Munich Ailabouni managed to reach the top 18 and started to dominate the competition by winning several castings. However, due to her shy personality, the judges questioned her limelight ability and saw her struggling several times when she was required to perform out of her comfort zone. For a long time she was the only non-German top 3 finalist of Germany's Next Topmodel, until cycle 10, where Ajsa Selimovic, who lives in Austria, managed to reach the top 3. In the final Alisar managed to win beating fellow-contestants Hanna Bohnekamp and Laura Weyel on a live final held in June 2010. She then appeared on the cover of the German Cosmopolitan in July 2010 and in a commercial for Venus Breeze, a job she won on the show.
Withdrawal from ONEeins contract
Like her predecessor Sara Nuru, Ailabouni did not win a contract with a known modeling agency. She was managed by Günther Klum's Management ONEeins but decided barely after a year to leave the contract due to her feeling that she was given only mediocre, no modelling related work. It marked the first time a winner of the show sued her way out of the contract and obligations not even one year after her victory.
Career
Ailabouni moved to Paris where she was taken under contract by PARS, the modelling agency of Peyman Amin who was a judge on GNTM but left before her participation. She also managed to get signed with other modeling agencies, Eskimo Models, City Models in Paris, Fashionmodel in Milan, Red in New York and Elite Model Management in London.
