Madonna celebrated 50 in London this weekend at an all night party organized by Guy Ritchie – supposedly – where he publicly declared his adoration for his wife and apparently presented her with a love letter reaffirming his commitment to their marriage and more adoptions.

Cutest detail? Lourdes serenaded her mother on the piano. Lola’s time is coming… Can’t wait.

Still, even though the festivities raged past 3am, still Madge would not allow herself a day off. She headed to the gym the next morning, weary but determined, and worked out for 3 hours. Must eliminate the calories from the night before.

Check her out, veins popping, her bum ankle taped tightly, hellbent on proving that age ain’t nuthin’ but a number.

Speaking of numbers, Madonna is 12 years older than Guy Ritchie. I am 12 years older than Michael Phelps. Which is still less than the 16 years between Demi Moore and Ashton Kutcher. Do I need to become a Kabbalist?
