Adam Lambert has released new track 'New Eyes' from his fourth studio album 'Velvet'.

The 37-year-old star took a break from his solo career four years ago to go on tour with Queen, before returning in February with the single 'Feel Something'.

He has now embarked on a new chapter with the release of the first single from his long-awaited follow-up to 2015's 'The Original High', a rock-influenced number, which has a ''romantic, earthy vibe'', and sees the 'American Idol' alumni - who has been dating Spanish hunk Javi Costa Polo for a few months - sing about having ''chemistry like candy'' and being ''naked and free''.

He belts out: ''This chemistry like candy to me/I'm addicted to the sweet, sleepy haze/ So whisper at me, get me wavy/ Naked and free, never no room for shame.''

Speaking about the track, the 'For Your Entertainment' singer said: ''I wanted my first single to reflect my current state of mind and to bring listeners into a romantic, earthy vibe. 'New Eyes' is a love letter to innocence and to finding new passions.''

The song is accompanied by a cinematic 70s-inspired video short directed by Miles & AJ, which will be followed up with Part 2 soon.

Announcing his ''new era'', Adam previously teased: ''A new era begins May 15th: My new single #NewEyes .''

When he announced 'Feel Something', Adam penned an open letter to his fans about a ''dark'' period he went through and admitted he felt like he was forced to ''compromise his artistic vision''.

He wrote: ''Let me offer a most sincere thank you for your patience and continued faith in me. You've pushed me to keep going even when I felt discouraged.

''I love making and performing music, but there have been many times where I've had to compromise on my artistic vision, with executives making decisions based on money and not art.

''Don't get me wrong--I'm VERY proud of my body of work. But I'm coming out of a dark period of second-guessing my own artistry and having my mental health suffer because of it. I started asking myself, 'Is all this hustle really worth it?'

''I put all my focus on work and started to feel detached in my personal life. My self worth was suffering, I was lonely, and becoming depressed.''

A full track-listing and release date for 'Velvet' is set to follow.
