Curvy Mariah Carey wears tight crimson gown for first red carpet appearance with James Packer at premiere... but pair appear tense after loved-up display for cameras

The beaming smiles were well justified on Monday evening as James Packer and Mariah Carey reunited on the red carpet for the premiere of new movie The Intern. 

Mariah was at her voluptuous best in a fitted crimson gown that accentuated her prodigious curves as she posed for photos alongside her Australian billionaire beau.

The soul diva looked delighted during their first red carpet appearance outside the Ziegfeld Theatre, which comes just weeks after the couple officially confirmed their romance during a protracted cruise around the Mediterranean.

At one point the businessman, a constant by Mariah's side throughout the night, hung back and checked messages on his mobile phone while the songstress mingled with fellow guests and chatted with assembled journalists.

The pair appeared to be animated and conversational during their outing, but Packer began looking more and more tense, especially at one point during a conversation with Mariah as they stood face to face.

His apparent mood appeared to intensify as they made their way inside the theatre, with the billionaire raising his hands up in protestation towards a woman as his glamorous girlfriend stood back, sunglasses firmly in place.

Steal Mariah's style in a dress by Azzedine Alaia

We've already seen pictures of this hot new couple on holiday together but last night was their first red carpet outing at the New York premiere of The Intern.

Mariah Carey is one of those women who is all about full on glamour no matter what the occasion so we're not surprised she went all out in a rather fabulous gown by cult designer Azzedine Alaia.

This French label is immediately recognizable thanks to the signature stretch knit that has made it so in demand. It clings in all the right places while acting as a soft corset so killer curves like Mariah's are dressed to perfection.

The full length version of this dress is not available online but click (right) to get hold of a mini version at Browns. Or recreate the burgundy palette with one of the dresses in our edit below. Starting at $60, they'll help you recreate Mariah's style without breaking the bank.

He recently told News Corp Australia: 'Mariah is just incredible, amazing she really is...She’s a genius'.

'Who else is there? There is Barbra Streisand, Whitney Houston and Mariah Carey. Not Madonna...Those three can sing five octaves...' 

Elsewhere the Sydney born billionaire has just seen new film Black Mass, on which he worked as executive producer, gross $8.8 million during its opening day in US cinemas, win a collective $24 million from worldwide ticket sales and earn a string of positive reviews.
