Since she started dating 30 year-old John Mayer, 39 year-old Jennifer Aniston has dropped nearly twenty grand a month on maintaining a youthful visage. The Enquirer says

“Her monthly regimen includes private instruction with a top yoga guru and personal training sessions. Jen pays a private chef for organic, high-protein, low-fat meals [and] goes for anti-cellulite sculpting treatments twice a month. She calls the treatments ‘necessary tune-ups.”

But all those tune-ups might not be doing the trick. Just two days before Jen flew to Amsterdam to meet Mayer, the singer was busy cheesing up some chick in a Dutch coffeehouse. According to In Touch

On June 20, John approached a writer from Manhattan Beach and sat beside her at her table. “I think he thought I was from Amsterdam, because he said, ‘I am John and I am a singer.’ I asked him what his relationship status was. He said, ‘It’s vague.’ I asked him what that meant and he said, ‘You know, it’s very vague.’ What she did say is that John was acting very much like a single man. “I never would have guessed he had a girlfriend at all. ”

Anti-cellulite spa sculpting treatments: $1,000. Thrice-weekly yoga session with top Hollywood guru: $3,000. Organic high-protein meals flown in by your personal chef: $3,500. Finding out your boyfriend cheated on you with some slut in fourteen dollars’ worth of Wet ‘n’ Wild from Walgreens: priceless. There are somethings that money can’t buy. For everything else, there’s actual self-esteem.
