Gisele Bündchen showcased her toned physique in a sleek black crop top while hitting the gym in Miami.

The 44-year-old Brazilian supermodel flaunted her flat abs in a black sports bra with crisscross straps, paired with matching black leggings, on Saturday.

Gisele completed her athletic look with tan sandals and accessorized with a water bottle, orange purse, and workout bag.

Her blonde hair was parted down the middle and cascaded down her shoulders, while she opted for a natural makeup-free look.

Gisele was also spotted in Miami on Friday after a gym session, donning high-waisted leggings that accentuated her slender frame.

She paired the leggings with a simple white t-shirt that was cut high enough to reveal her toned midriff, and accessorized with a bulging burnt-orange handbag.

The Brazilian bombshell swept her caramel locks up into a high bun, shielding her eyes from the sun with butterfly sunglasses.

Gisele recently posted a heartfelt 17th birthday tribute to her stepson Jack, nearly two years after her divorce from his father Tom Brady.

Gisele had been dating Tom for two months when they discovered that his ex-girlfriend Bridget Moynahan was pregnant with Jack.

The three adults managed to establish an amicable co-parenting relationship, with Gisele referring to Jack as her ‘bonus child’ and herself as his ‘bonus mom.’

Tom and Gisele were married in 2009 and welcomed two more children – Benjamin, 14, and Vivian, 11 – before she divorced him in 2022.

When Jack turned 17 on Thursday, Gisele posted a sweet snap of her hugging him when he was a little boy, captioned: ‘Happy Birthday to this sweet peanut!’

Her follow-up post showed Jack much more recently, embracing Gisele and towering over her, despite the fact she herself is 5’11”.

‘Who turned into a beautiful, kind, and incredible young man,’ she wrote. ‘We are so lucky to have you in our lives! Love you so much.’

Gisele has previously remarked that she is ‘so grateful’ for Bridget, while admitting that the timing of the pregnancy news ‘wasn’t the ideal situation for anyone – there’s no manual to prepare you for that.’

‘I know this was hard, but I couldn’t imagine my life without [Jack]. I call him my bonus child. He opened my heart in ways I didn’t even know my heart could expand. I fell in love with him,’ Gisele recalled.

Her bond with her stepson fueled her own desire ‘to start a family,’ in part because she ‘wanted Jack to have a brother or sister close in age.’

Gisele and Tom announced their divorce in October 2022 after a swirl of reports that their marriage was on the verge of collapse.

She was claimed to be livid over Tom’s shock decision to ‘un-retire’ from the NFL – just one month after he gave up football to spend more time with his family.

‘Obviously, I have my concerns – this is a very violent sport, and I have my children and I would like him to be more present. I have definitely had those conversations with him over and over again,’ she told Elle shortly before their split went public.

‘But ultimately, I feel that everybody has to make a decision that works for [them]. He needs to follow his joy, too,’ Gisele added.

Tom initially announced his departure from the NFL during the 2022 off-season – only to perform a dizzying volte face and return to pro football a month later.

He officially retired again at the beginning of last year after his marriage collapsed, and he has remained out of pro football since.

Gisele has moved on with her steamy jiu-jitsu instructor Joaquim Valente, though she has staunchly denied that she cheated on Tom with him.

Meanwhile Tom has been linked to a string of names like Kim Kardashian, Irina Shayk, Emily R
