A$AP Rocky sweetly referred to pregnant Rihanna as his 'wife' as she supported him at his Cannes Lion Festival show in France on Wednesday. 

In video obtained exclusively by DailyMail.com, the songstress, 35, slowly grooved to the sounds of the rapper, 34, performing on stage at the Spotify Beach bash.

An onlooker said of the pop singer: 'She ended up dancing the night away and was in high spirits all evening. She spent time chatting to other guests at the party including Tiffany Haddish.'

And during the show, A$AP gave a sweet mention to Rihanna, telling the crowd: 'I'd like to dedicate this song to my beautiful wife in the motherf***ing building!'

Rihanna had one hand resting on the balcony railing as she watched the show from afar, her head nodding along to the music.

Oh baby! Pregnant Rihanna flaunted her bump in a sheer catsuit and bikini top as A$AP Rocky called her his 'wife' at his Cannes Lions Festival show on Wednesday night

Rihanna and A$AP Rocky welcomed a son last year in March and are currently expecting their second child.

Last month DailyMail.com revealed that the pop star named her son RZA Athelston Mayers after exclusively obtaining a copy of the little boy's certificate of live birth.

The child was apparently named in honour of the producer and rapper RZA from Wu-Tang Clan.

Fans had recently speculated that the little boy might have been named Noah, but there were few indications of his true name for nearly a year.

She revealed that she and Rocky were expecting again when she debuted her bump during her show-stopping Super Bowl halftime performance on February 12 in Glendale, Arizona.

During her stunning appearance at the Met Gala with her boyfriend, Rihanna shared with ET that her latest pregnancy was 'so different' from the first one. 'No cravings. Tons of nausea. Everything's different, but I'm enjoying it,' she explained.

She added that she was 'in love' with her littlest one. 'I'm obsessed, and I don't even feel guilty about it,' she said.

Had a blast! And during the show, A$AP gave a sweet mention to Rihanna, telling the crowd: 'I'd like to dedicate this song to my beautiful wife in the motherf**king building!'

Rihanna is being similarly tight-lipped about baby number two, and she has not yet revealed its sex.

It's unclear if Rihanna plans to be as secretive about her second child's name.

Rihanna and A$AP Rocky have been friends and collaborators for more than a decade, and they even attended red-carpet events together in recent years, but it wasn't until late 2020 that they officially became a couple.

After the Super Bowl and pregnancy reveal, the couple appeared on the March cover of British Vogue, where Rihanna gushed that Rocky is her 'best friend' and admitted she can't remember what her life was like before having her son in May 2022.

She said of becoming a mother: 'It's everything. You really don't remember life before, that's the craziest thing ever.

'

The singer added that motherhood also emboldened her, leading to her accepting the Super Bowl gig just months after having her first child... and seven years after she last performed on stage.

'It's this knowing that you can do anything, even things that seem the craziest, like, 'I'm going to say yes to the Super Bowl in the middle of postpartum?'' she said

'What the heck am I thinking? But you're geeked on a challenge like that because you know what your body just did. You feel this sense of 'Nothing is impossible,'' she said.
