Sarah Harding cuts solemn and solitary figure as she takes dog Corker for a walk in the park

Why so glum Sarah Harding cuts a solemn and solitary figure as she takes dog Corker for a walk in the park

She's spoken of her love for him ever since they called off their engagement last year.

So Sarah Harding should surely be ecstatic after reportedly reuniting with her former fiance Tom Crane last month.

But the Girls Aloud singer looked far from happy as she stepped out with her beloved dog Corker on Tuesday.

The pop star appeared to have the weight of the world on her shoulders as she walked along in the freezing weather.

Wearing an all black ensemble, Sarah teamed up a pair of skinny jeans with a T-shirt and leather knee-high boots.

But despite donning a long black padded Puffa coat with a fur collar, Sarah still seemed to be feeling the cold as she left the jacket open.

And her mind seemed to be somewhere else as she hid her eyes behind dark sunglasses.

Scraping her blonde locks back into a high bun, the 30-year-old put her hands across her chest while wearing some fluffy white gloves.

And she obviously had more important things to think about as she stepped out in grubby trousers, probably from Corker's paws.

She was enjoying some alone time with her pet pooch in a North London park.

But the beauty has reportedly rekindled her romance with her DJ beau.

As we reported last week the pair were spotted heading to a supermarket near her home, before heading back to her house.

The outing sparked rumours they are giving their love another go – and now apparently they have.

A source tells heat magazine: 'Tom's been round a lot. They're giving things another go, but very tentatively while she gets better.'

The lovers reportedly decided to work things out after Sarah decided to seek help for her alcohol addiction and depression issues.

Another insider tells the publication: 'Sarah and Tom just can't be without each other. They split because of their arguing, but that's really improved since her trip to rehab.'

But although they have started to patch up their relationship, the formerly engaged couple won't be rushing to head down the aisle any time soon.

'They're taking things slowly this time. The wedding's not back on yet. They haven't ruled it out, but it's going to take time.

'Sarah still needs to sort her head out, but she feels better knowing that Tom's behind her.'
