It can be tricky to maintain perfect locks while at Glastonbury festival, even for those enjoying the hospitality tents the event has to offer.

And on Sunday Prince Harry’s ex-girlfriend Cressida Bonas showed that even she can’t be immaculately groomed at all times.

The 25-year-old was seen with tousled bedhead hair as she prepared for the festival’s final day, following reports from Mail On Sunday about her spending time with Will Poulter during the event.

Morning! Cressida Bonas was spotted strolling around Glastonbury festival on Sunday

Festival girl: Cressida looked cool wearing a pair of denim shorts and a Hooters T-shirt

The pretty blonde fitted into the festival vibe perfectly wearing a pair of cut-off denim shorts and grey Hooters T-shirt.

Despite the sunnier weather Cressida, called Cressie by those close to her, sensibly wore a pair of wellington boots.

Indicative of her extended stay at the festival, her hair – pulled back from her face in a half ponytail with a scrunchie – appeared to be somewhat tangled.

Not worried: Cressida showed just how down to earth she is wearing muddy wellies as she strolled around

On Saturday, she was spotted having a lighthearted chat and laugh with actor Will Poulter after reportedly ‘partying’ together the previous night, and they appeared to have a great rapport.

The fresh-faced 21-year-old boy is best known for starring in 2013 film We’re The Millers alongside Jennifer Aniston.

A source told the paper: ‘They were all over each other in the hospitality area.

Hanging out: Harry’s ex was joined by a pal who she wrapped her arms around

‘Everyone was talking about how close they looked. It was all very exciting. They looked like they were having a really great time.’

Another pal said: ‘It was snug in the hospitality bar. When the rain came down everyone had to huddle together, but there was no doubt that Will and Cress were closer than they needed to be.’

Later, the pair snuck away to Glastonbury’s exclusive nightspot The Rabbit Hole, which is open only to a special few who know where it is.

A spokesperson for Will declined to comment.

Saturday saw Lily Allen ,as well as Lana Del Ray, who belted out the lyrics to ‘Young and Beautiful’ followed by tracks such as ‘West Coast’ from her new album ‘Ultraviolence’.

Metallica performed their classic hit ‘Creeping Death’, which had fans violently head-banging along.

Performers on Sunday will include Dolly Parton, who said: ‘I’m just a country girl and now I feel like a rock star’ ahead of her much-anticipated set at Glastonbury.

The Jolene singer was speaking as she was presented with an award backstage at the festival in recognition of her having sold 100 million records worldwide.

Glastonbury organiser Michael Eavis, 78, has hailed this year’s festival as a ‘great success’ and said he already has next year’s headliners sorted.

The farmer, who put on the first festival at his farm in 1970, was sworn to secrecy about who the acts were, but said one band was not British and Prince was not among them.

He said the 44th festival had been a ‘great success again, in spite of the mud and everything’.

‘But we have had wetter years than this,’ he added. ‘Everybody loves it – the fans that come, the bands that played. The best place to be really basically.’
