Jennifer Aniston is so grateful for her amazing figure that she’s launching a DVD for her yoga instructor, Mandy Ingber. Aniston has jetted back from her Moroccan break to host a party for Ingber’s DVD Yogalosophy at the Sunset Towers hotel in LA on Thursday. Aniston — who previously admitted she practices yoga to “quiet her mind” — has even filmed a personal introduction for the video. She says, “Mandy brought yoga into my life. This workout will change your body and your mind.” The DVD is inspired by a yoga feature that Aniston and Ingber did for Self magazine in 2006. A source told Page Six, “Jen works out with Mandy up to five times a week, and they have become such great friends she even takes Mandy on vacation with her. So Jen was delighted to help launch her DVD.” Guests expected include Aniston’s best friend, Courteney Cox, and Self Editor-in-Chief Lucy Danziger.
