Charles Leclerc and Alexandra Saint Mleux spark marriage rumours a week out from Aussie Grand Prix

Formula One is set to make its grand return for 2026 at the Australian Grand Prix this weekend – but it appears as though team Ferrari's Charles LeClerc may already have something to celebrate.

Speculation regarding the racing ace's marital status has heated up, after LeClerc, 28, and influencer girlfriend Alexandra Saint Mleux, 23, were spotted clad in matching white ensembles in Monaco over the weekend.

Footage currently circulating on social media shows Leclerc behind the wheel of a 1957 vintage Ferrari, with Saint Mleux sitting shotgun clutching a small bouquet.

The couple are yet to officially confirm these rumours, however Saint Mleux has further fuelled online frenzy after quietly changing her name to 'Alexandra Leclerc' on Instagram.

Saint Mleux also posted a series of snaps last week, which showed her donning a bridal-esque white gown and clutching a bouquet of red roses – seemingly alluding to her upcoming nuptials.

The pair's rumoured marriage comes off the back of a fast and furious three-year relationship, during which Saint Mleux has become a standout fixture amongst the F1 WAG circuit.

Their romance culminated in the announcement of their engagement four months ago, wherein they posting a picture-perfect carousel of snaps alongside their beloved pooch Leo.

The series of photos placed Saint Mleux's dazzling rock front-and-centre – not that the whopping oval-set diamond was difficult to spot – which is reportedly around 5-6 carats, with an estimated value upwards of $525,000.

Their beloved long-haired dachshund evidently played a central role in the proposal – with one image showing the pup bedazzled in a gold pendant collar reading "Dad wants to marry you".

Leclerc – who is reportedly worth around $125million – spared no expense, presenting a lavish set-up of rose petal hearts, candles and bouquets for the occasion.

Saint Mleux, meanwhile, was the picture of happiness, glowing in a periwinkle blue silk sheath dress.

The model and influencer was first linked to Leclerc in March of 2023, when eagle-eyed fans caught a glimpse of her in the background of a Tiktok posted of the F1 Star at Paris Fashion Week.

The rumours were further solidified in May, when she was spotted in attendance at the Monaco Grand Prix as a guest of Ferrari.

While mostly preferring to keep their relationship low-profile, the couple officially went public after stepping out at Wimbledon in 2023.

The star driver will return to the fray this coming weekend, as the Formula One Australian Grand Prix kicks off in Melbourne.
