Sarah Harding couldn't cope with Cheryl Cole's career.

The 28-year-old singer is impressed with the way her Girls Aloud bandmate is juggling a career as a solo artist and judge on UK TV talent show 'The X Factor' while the group are on hiatus but thinks she would be "dead as a dodo" if she tried to tackle a similar workload.

Sarah - who has embarked on an acting career during her time off from the band - said: "I don't know how Cheryl does it. She's not stopped. I went straight into doing the 'St. Trinian's' movie and we've all kept ourselves busy but not at the sort of pace she has. I would be dead as a dodo."

Since Girls Aloud went on hiatus at the end of 2009, the 'Biology' hitmakers have been dogged by rumours that Nadine Coyle - who resides in Los Angeles - will quit the group permanently to embark on a solo career and Sarah refused to address the speculation.

She told Britain's OK! magazine: "I can't comment about that, sorry. Don't believe everything you read, that's all I've got to say."

The blonde beauty has enjoyed her time outside of the band - which also consists of Nicola Roberts and Kimberley Walsh - and although they are expected to reunite in the near future, Sarah still has acting ambitions she wants to fulfil.

She said: "I've really had a lot of fun getting some acting experience. I'd love to act in the place that they shot 'Twilight' in, Portland, Oregon.

"I'd love to go up there - I just like the scenery, the countryside and all the greenery there."
