Demi Lovato's Tell Me You Love Me tour has already proven to be quite raunchy.

But Lovato took it to another level when she locked lips with her tour opener Kehlani, 22, at her New Jersey concert.

Already on a prop bed and dressed in sexy white lingerie, the 25-year-old singer laid Kehlani down to then straddle and serenade her.

'Truly so grateful to have had this extremely special, talented, and cool as f*** woman on this tour with me,' the sultry songstress later said in an Instagram post. 'What an incredible fun, sexy, crazy night that I’ll never forget!!'

Kehlani was one of two openers for the domestic leg of Demi's tour.

'Twas a dream getting to do this tour with you,' Kehlani gushed on Instagram.

'Watching you every night was a learning experience and you forever have a fan and supporter in me. Tonight your dancers put me up to this but anyone would be stupid not to jump at the chance to hop on that damn moving bed and grab your face looooool.

'I love you and appreciate you, beautiful. Cheers to you, more life and success on the rest of the legs of this tour.'

'I think love is love,' she said. 'You can find it in any gender. I like the freedom of being able to flirt with whoever I want.

'I'm normally the first one to make the move. I'm always the one who says, 'Let me get your number.' Or I slide into their DMs on Instagram.'

Fan love! Demi participated in a meet and greet on Monday night before her show

Lovato was last linked to Guilherme 'Bomba' Vasconcelos—an MMA fighter. But that brief courtship has nothing on her six-year relationship with actor Wilmer Valderrama that ended in 2016.

And Kehlani may have some competition as Lovato hinted to still having feelings for her ex during confessionals for her YouTube documentary Simply Complicated.

'I think my heart is always with Wilmer, I think it was with Wilmer, I think it is with Wilmer, I think it will be,' she shared.
