Sarah Harding's relationship is taking its toll on her waistline.

The 33-year-old singer-and-actress is smitten with boyfriend Jason - who she has been dating for three months - but admits cosy nights in has affected her slim figure.

She said: ''Things are going so well with Jason. I'm really happy right now.

''I'm feeling really good but I've put on weight. Being in a relationship is terrible for your waistline.

''After all those nights in with takeaways, I've got an overhang on my belly. But it's not a bad thing. You're more relaxed when you're loved up and I know I'm still slim.''

While Sarah used to be renowned for her wild partying, these days she's never happier than when she's in her garden.

She told Closer magazine: ''If I get a day off, I'm in the garden.

''It sounds boring but I just enjoy getting my hands dirty and working on my vegetable patch.

''I wanted to do some gardening recently but it rained - typical England, you can't rely on the weather.

''I'm the type of person who needs to be busy. When I stop, that's when I drop. I need to be on the go. I can't sit still.''
