Turning heads on her night out in Hollywood, Mariah, 47, appeared completely ageless as she showed off her flawless complexion, before joining ex Nick Cannon inside.

And the star went for her usual glamour with a diamond necklace and huge matching earrings, as she joined stars at the MC Records Launch Party.

The singer towered in strappy heels and wore her hair in loose curls.

On closer inspection, Mariah kept a subtle nude under-layer on below the split side to avoid any awkward malfunctions.

Mariah and Nick have been spending a lot of time together recently, following her split from Bryan Tanaka, but it’s unclear if they’re just remaining close for their kids.

Meanwhile, the US superstar’s inner circle are taking no risks in their bid to stop her getting back together with toy boy Bryan Tanaka.

The Sun exclusively revealed the diva had her phone confiscated to prevent her from contacting the dancer, who she began dating after the end of her relationship with billionaire fiancé James Packer.

Bryan has been locked out of Mariah’s home and even blocked from re-entering by security.

But he has told pals that Mariah wants him back and that she is having a meltdown over it.

A source said: “Mariah has been in a good place since the split and her team are worried Bryan could harm her wellbeing should they get back together.

“They’ve gone all out to stop it from happening, taking some drastic steps.

“Bryan is convinced Mariah is still in love with him, and the fact he believes she is having some sort of breakdown has only increased his determination to contact her.”Mariah dumped Bryan last month after a whirlwind five months together, much to the relief of her team.
