A SOUTHAMPTON singer - and his dancing grandma - stole the show as ITV'S new series of the Voice made its debut.

Donel Mangena, 16, impressed coaches with his version of Major Lazer's Cold Water on the show last night.

And unusually, he got a little help from grandma Nita, who rushed the stage to celebrate with some dance moves.

Delighted viewers took to social media to show their appreciation.

One wrote: "I want Donel's grandma to be my grandma", while another said: "It's no wonder Donel Mangena's grandma came and invaded his performance.

"His name is an anagram of 'Me Golden Nana'."

Overnight data shows the launch episode of the singing programme, which saw new coach Olly Murs make his debut, was watched by an average of 5.6 million viewers and had a 27.6% audience share, ITV said.

The audience peaked at 6.1 million viewers during the broadcast, which aired from 8pm until 9.35pm.

Overnight figures include those watching on ITV+1.

The new series' first episode was slightly down in the ratings compared to the equivalent from last year.

The launch show in 2017 was viewed by an average of 5.9 million and peaked at 6.9 million according to the overnight ratings.

But it still marks a boost from when the talent show aired on BBC One the previous year, with an average of 3.2 million viewers for the same slot.

On Saturday, The Voice UK clashed with portions of BBC One's Wedding Day Winners and then Casualty, which were watched by an average of 2.3 million and 3.8 million viewers respectively.

Murs, who replaced previous coach Gavin Rossdale, appeared along with returning panellists Jennifer Hudson, Sir Tom Jones and Will.i.am.
