Rehab and the news that Girls Aloud are reforming have certainly put a smile on Sarah Harding’s face.

She was seen looking happier than in previous months in trendy Primrose Hill, close to where she lives, yesterday (June 17th).

Looking casually cool in a CND grey sleeveless T-shirt and purple trousers, Harding had a big grin on her face.

She teamed her outfit with a pair of oversized sunglasses, making the most of the rare snippet of sunshine that we had yesterday, and tonnes of jewellery.

Harding rocked a heart-shaped pendant and simple silver chain necklace as well as a chunky silver bracelet and two rings.

It is thought that Girls Aloud are back in the recording studio to lay down a new album to commemorate the girl band’s tenth anniversary.

The 30-year-old’s band mate Cheryl Cole recently told Radio One DJ Chris Moyles: “It’s coming up to our tenth anniversary in November and we all want to do something to celebrate it, so watch out!”
