Billie Piper has told London's Evening Standard newspaper that her West End debut has been "amazingly stressful".
The 'Doctor Who' star, who suffered from gastric flu and missed performances in the run up to the opening night of 'Treats' said:
"It's my first time on the West End stage and I've never done it before - it's hardly surprising that it's going to be really terrifying."
She denied rumours that she is going to marry her new boyfriend actor Laurence Fox, saying that she is not yet divorced from her ex-husband Chris Evans.
Fox is also her co-star in 'Treats', along with Chris Marshall.
