Adele Posts No Makeup Selfie On Twitter For World Water Day

We've barely heard a peep from Adele since she welcomed her son Angelo 17 months ago.

But the star took to Twitter on Saturday and posted a pic of herself enjoying a nice cuppa to mark World Water Day.

What's more, she did it makeup-free! The Oscar-winning singer-songwriter wrote: #iLoveWater and so does #drop4drop get involved at it's world water day!

The collage picture also featured her goldfish bowl, using the tap, and her son reaching for his beaker.

In another tweet, she wrote: "Everyone tweet a picture of yourself with water! Drinking, showering, cooking, cleaning... #iLoveWater."
