This Morning viewers left cringing over Holly Willoughby's bizarre return

This Morning viewers have been left cringing over Holly Willoughby's... interesting return to the show.

The ITV presenter - who previously hosted the morning talk show alongside co-host Phillip Schofield - usually takes around two months off every year for her summer holidays and gave viewers a final farewell ahead of her annual break back in July.

Now back from her time off, Willoughby's grand return involved some boogying, singing and a whole of of ABBA. Check it out:

The long-awaited This Morning ceremony took place in White City Studios under the beaming sun today (4 September) as the host partnered up with Alison Hammond for the big reunion.

The pair can be seen getting their groove on to 'Dancing Queen' alongside the cast of Mamma Mia.

It's clear, however, that the pair's upbeat festivities weren't totally embraced by viewers at home, as many have since taken to social media to share their gripes with it.

One Twitter user hit out: "They couldn't have possibly opened the show worse than this."

"This is it, we’ve reached peak cringe," declared a second.

A third claimed: "I've had surgeries more enjoyable than this."

Ouch.

A fourth viewer added: "It's too early for this cringefest!"

"Bit of a false 'Look at us and what good friends we are, giggle giggle!' Actually it's a bit cringe," echoed a fifth.

"What the actual f**k," penned a final Twitter user.

Despite the criticism, it's clear ITV are happy to continue putting Willoughby front and centre for the channel.

"Holly is the future and ITV wanted to make that clear. It's a sure sign that she is at the helm and the other presenters will join her," a source told The Mail on Sunday.

"It's a brand new start for This Morning, the scandal could have destroyed it but it has managed to keep going. There is a lot of excitement."

This Morning has entered what Willoughby has referred to as a 'new chapter' following Schofield's departure which came shortly before he admitted to having an affair with a younger colleague.

Amid the constant rotation of presenters joining the programme to help Willoughby with her presenting duties, viewers have been treated to the likes of Dermot O'Leary, Josie Gibson and, fan-favourite, Craig Doyle.

Willoughby took her annual two-month break for the year earlier this summer (6 July) and has now returned to her presenting duties for the season.
