Adele Gives Rare Glimpse Into Her Private Life, For A Good Cause

Adele has achieved international superstar status at the tender age of 20 but she has managed to keep her personal life almost entirely private in the five years since. Until now, that is.

Promoting World Water Day on Saturday, March 22, Adele posted a four photo collage to her Twitter account. The clues we can glean are few but precious: Adele has a small fish tank, Adele looks positively stunning without makeup, and Adele's 17-month-old baby boy Angelo is growing up so fast!

Gwyneth Paltrow, Britney Spears, Bar Refaeli and Katy Perry have also endorsed the important cause, aimed to provide clean water to the 800 million people who lack access to it, on social media this weekend.
