(femalefirst.co.uk) - Jennifer Aniston has reportedly been spending ?4,000 a month on her appearance.
The 39-year-old actress is allegedly worried her younger boyfriend, John Mayer, 30, will leave her for a younger woman and so has been splashing out to maintain her looks and figure.
The astonishing sum reportedly includes ?1,000 on a personal chef and ?750 for one-on-one yoga sessions with Los Angeles' top instructor, Mary Ingber.
A source revealed: "Jennifer doesn't have time to prepare her own healthy meals, so she's signed up with this organic, high-protein, low-fat meal delivery service."
Jennifer has reportedly been shelling out on beauty treatments costing her hundreds of pounds a time.
The source added to Britain's Grazia magazine: "Jennifer has been spending ?750 a month on seaweed and oxygen facials. She claims they instantly erase lines, dark spots and puffiness.
"Amazingly, she doesn't have a trace of cellulite. And now it seems she's become more scrupulous about her thighs, having anti-cellulite spa sculpting treatments that cost about ?500 a month. She's also been spending around ?350 on exfoliating body wraps. "Jen invests up to ?300 a month on maintaining her hair too."
Also on Jen's list are personal training sessions, manicures and pedicures at ?150 per month and ?100 a week on massages to ease stress.
