Rihanna – who already has sons RZA, two, and Riot, 21 months, with A$AP – looked sensational in a racy black cut-out dress as she headed out in the south of France.

It comes after on Monday night Rihanna showed off her blossoming baby bump yet again as she supported A$AP at the Cannes Film Festival premiere of his new movie Highest 2 Lowest.

She looked happy and healthy as she made a typically late arrival to the red carpet.

The star looked great in a ruffled blue dress and strappy heels as her partner sweetly put her arms around her.

They were hit by some bad weather in Cannes however as they walked some of the red carpet in the pouring rain. 

A$AP looked smart by her side as he showed off his sense of style in a black suit and shades.

Highest 2 Lowest is directed by Spike Lee and follows the story of a music mogul who faces a life-and-death moral dilemma when he gets caught up in a ransom plot. 

It stars Denzel Washington, Ilfenesh Hadera, Jeffrey Wright, Ice Spice (in her film debut), and A$AP.

Earlier this month Rihanna insisted her new album won’t be delayed too much by her pregnancy.

She confirmed the happy news at the Met Gala and some fans were wondering if it will impact her long awaited record.

Speaking to Entertainment Tonight, the Umbrella hitmaker was asked if the album – which has been dubbed ‘R9’ – will be ‘put on pause even longer’.

She said back: ‘No, maybe a couple of videos.’

Fans have been waiting nine years for the collection, but RiRi hinted plans are still in place.

She then quipped: ‘I can sing!’

Rihanna also revealed she isn’t ‘too overwhelmed’ by her pregnancy, although there was some initial shock.

She added: ‘I’m good! I’m shockingly feeling ok, and not too overwhelmed at the moment. At first it was kinda like, ‘Ahhh!’ ‘

In the meantime, fans are still waiting for the follow-up to 2016’s Anti.

While details are few and far between, in February she offered a tease of what fans can expect from the album.

She told Harper’s BAZAAR magazine: ‘I’ve been in the studio the whole eight years. But it didn’t hit me. I was searching for it.

‘I went through phases of what I wanted to do. ‘This kind of album, not that album’. I know it’s not going to be anything that anybody expects.

‘And it’s not going to be commercial or radio, digestible. It’s going to be where my artistry deserves to be right now. I feel like I’ve finally cracked it, girl!’

Rihanna insisted there was ‘no genre’ for the album, and she has been determined to make the next batch of songs something ‘matching [her] evolution’.

She added: ‘After a while, I looked at it, and I was like, this much time away from music needs to count for the next thing everyone hears.

‘It has to count. It has to matter. I have to show them the worth in the wait.

‘I cannot put up anything mediocre. After waiting eight years, you might as well just wait some more.’

At the Met ET’s reporter then asked whether Rihanna and her boyfriend, ASAP Rocky, had any other news to share, like a secret wedding.

‘No, girl, you don’t know I keep secrets very well,’ the Fenty Beauty founder replied.
