Holly Willoughby appears glum as she walks past rubbish sacks on a dog walk

Holly Willoughby looks glum on quiet dog walk with beloved pup Bailey… days after dressing up as a VERY happy Barbie at Keith Lemon’s bash

She dressed up as Margot Robbie’s interpretation of Barbie this weekend.

Yet Holly Willoughby was a million miles from ‘living in plastic, it’s amazing’ on Monday morning when she walked her beloved dog Bailey on the streets of London, where she passed a large pile of rubbish.

After donning a form-fitting pink jumpsuit and sporting a cowboy hatred for Keith Lemon’s star-studded 50th birthday dress, the This Morning host went extremely low-key in an altogether more muted ensemble.

With her Golden Retriever Bailey in tow, the blonde beauty, 42, stepped out in a waxed Barbour jacket, loose jeans, chunky boots and sunglasses.

Her weekend ensemble was a take on one of Margot’s costumes in the new Greta Gerwig-directed Barbie movie, due out in July.

Holly brought her husband Dan Baldwin into the action and was flanked by her own take on Ken – who is played by Ryan Gosling in the movies.

However, it was back to reality on Monday when a very serious Holly was out for the dog walk with Bailey in her muted ensemble.

Her outing comes after she suffered a bout of shingles last month. Holly gave fans a health update after being absent from This Morning due to illness.

While she didn’t confirm the day, she suggested she’ll be back on screen once she says she’s “feeling so much better.”

The host took to her Instagram Stories to thank fellow This Morning star Dermot O’Leary, 49, for sending her some soup and a Reuben sandwich as she recovered.

Sharing part of her meal, she wrote, “Thank you @dermotoleary for the sweetest delivery of chicken soup and cured beef… just what I needed.” Feel so much better. Thank you all for your good wishes.’

Holly would welcome Phillip Schofield back to the ITV daytime show that week, having taken time off during his brother Tim’s sexual assault trial.

When she recovered, Holly assured viewers a week later that she was completely healthy again, saying, “I’m much better.” I had a wobbly week and a half. It’s no fun for anyone who’s had shingles. But I am fully recovered and back. Nice to see you!’

The pair then said how happy they were to see each other before moving on with the programme, which began with a segment about a London marathon runner dressed as Captain Scarlett.
