Amanda Holden teased her upcoming single release by dropping a sultry snap on social media.

The Britain's Got Talent babe, 49, looked gorgeous as she rocked a glamorous strapless floor-length gown.

With her hands resting on her hips, the mum-of-two candidly looked away from the camera as the garment hugged her figure in all the right places.

The ensemble featured a sweetheart neckline around her bust area, and a waistband that clinched in her slim figure.

As always, the TV presenter oozed radiance, sporting a sun-kissed glow, and glossy tresses.

She captioned the snap: “Tune into Heart FM tomorrow for a world premiere of ‘With You’! my new single from my debut album "Songs From My Heart".

And it wasn’t long before she was inundated with compliments from her 1.5million followers.

One wrote: "Oh my goodness look at you!"

"You look so gorgeous," another added.

The mum-of-two reportedly signed a £1million recording contract

Amanda signed a reported £1 million record contract, and recently opened up about her new music, explaining that the song With You is a tribute to her son, Theo, who was stillborn in 2011.

Discussing the track with The Mirror, Amanda admitted that she finds it "very emotional" to sing the highly-personal song.

She said: "The last lines of this song are ''You took my life with you, Took my world with you'' and so this is for Theo, our baby who was born sleeping and for Chris who stayed strong when I fell apart.

"It was Chris who told me he always thought of Theo when he heard this song which floored me so it's also his song for Theo."

She added: "It's very emotional to sing this song but I think you get chosen for experiences like that only if you are strong enough to deal with it. And it changes you."

Amanda will also be seen on Britain's Got Talent this weekend as the show returns to ITV.
