She's known for her saucy persona but it seems Rosie Webster's antics may cause a few accidents.

The Coronation Street resident was spotted getting frisky in a van today but all didn't end well.

Helen Flanagan, 21, who plays the manipulative character was seen filming some intimate scenes with her onscreen lover Jason Grimshaw - played by Ryan Thomas.

Getting steamy: Jason Grimshaw (Ryan Thomas) and Rosie Webster (Helen Flanagan) film scenes in a white Transit van today

The builder isn't too pleased when he has to stop to get diesel for his van in the pouring rain and leaves his girlfriend sitting in his white van.

However, Rosie being who she is decides to try and cheer up her boyfriend when he returns, and the two end up getting quite frisky in the front of the van and doesn't seem to care who can see them.

Still wearing his fluorescent high-visibility jacket, Jason gets carried away with his model girlfriend and the pair end up letting the handbrake go.

But before they notice that the van has been rolling forward, it's too late and they've already smashed into a parked car.

The pair no doubt want to make a quick getaway following the crash but with a driver sitting in the car in front, there's little chance that they're going to get away with it - unless Rosie can use her manipulative charm to talk him round.

Actress, Flanagan, was spotted on set after they filmed the scenes and looked very glammed up as usual.

Wearing a short navy blue skirt with a green top and towering black heels, the brunette kept herself warm by wearing a faux fur coat.

Flanagan is set to be filming her final scenes this for the ITV soap this month after revealing that she wouldn't be renewing her contract.

She has played the whining character for 11 years but admitted she will be moving to Swansea to be with her footballer boyfriend Scott Sinclair.

In a recent interview, Flanagan also stated that she wasn't sure how Rosie will be written out of the show but presumes it will be down to her wanting to pursue her glamour modelling career.

She will be seen on the small screen until February next year.
