Aston Merrygold has dropped his new single, amid rumours he may be unmasked as Robin on The Masked Singer finale.

The JLS star has shared the lyric video to his new song Overboard, his first solo effort in two years.

A different flavour to Aston’s signature solo track Get Stupid, Overboard is a mix of old school R&B and pop.

The 33-year-old said: ‘I’m very excited to be releasing Overboard. It’s great to have been back in the studio working on new music, and there’s more to come as well! 

‘I can’t wait to see you all soon, when it’s safe to do so.’

Fans and friends including Alexandra Burke shared their excitement at the track release, with his X Factor pal leaving fire emojis under the Instagram announcement.

However, the timing may seem a bit suspicious for The Masked Singer sleuths, who reckon the popstar is in Robin’s costume.

On tonight’s grand finale, we will finally find out the identities of Robin, Badger and Sausage, with one of the mystery celebs being crowned the winner.

Since week one, viewers have guessed that Robin is Aston, with the singer the bookies’ favourite to be behind the mask.
