It is said that the advice has helped their love life.
The 33-year-old is said to be more intimate with her fiance since they started getting advice from the expert in the Indian arts of Tantra meditation, reports femalefirst.co.uk.
Tantra is described as more like a yoga session mixed with couples' therapy. They do breathing exercises and then the therapist encourages them to discuss their fantasies.
A source said that Simpson swears she has more energy and added: "Her skin is constantly glowing. She's telling friends she's found the fountain of youth."
The couple has two sons - 19-month-old Max and six-month-old Ace.
