Bella Hadid flaunts her flat stomach in a sheer crop top with leggings as she jets out of LA with mother Yolanda

There was no mistaking model Bella Hadid and her mother Yolanda on Sunday as the glamorous duo waltzed into Los Angeles airport.

Bella, 19, flashed her tummy in a black crop top and leggings as she walked through the terminal ready to check in for a flight to London. 

The teen also flashed her bra in the slightly sheer top and wore her dark locks slicked back in an immaculate bob.

Yolanda, 52, wore a contrasting look to her youngest daughter in an all-white outfit.

Orange flats and a matching handbag added a colourful accent to her look. 

This week Bella underwent an IV treatment for Lyme disease and documented the experience via Snapchat.

Yolanda was diagnosed with the disease and has been publicly documenting her battle with it for the last few years.

She revealed last year that her youngest daughter and her son Anwar had also been diagnosed with it.

Gigi, 21, and also a model, is the only member of the family who hasn't been affected by it.

Last week, Yolanda underwent surgery in a bid to finally conquer the debilitating disease, having what is known as a Transvascular Autonomic Modulation (TVAM) procedure.

Get some classic Puma kicks like Bella

Somethings never go out of style for Bella Hadid. Looks like she's still in love with sneakers and that sports luxe look. We spot her in an crop top and yoga tights look that are finished off with a pair of classic Pumas.

That's an excellent way to achieve that so trendy Athleisure vibe. These sneakers have been around for a while and they're not going anywhere because it's such a timeless piece that you can dress up or down. Pair these with a neoprene skater dress for a girlish athletic look.

Shop the exact style she is wearing via Zappo's for $55.

TVAM is a relatively new procedure which has been suggested as a treatment for those suffering Multiple Sclerosis and other autoimmune disorders. 

Bella praised her Real Housewives Of Beverly Hills star mother on Instagram in June for always being there for her.

'I have been struggling with Lyme and other co-infections for the past two years which has debilitated me from riding my horses, going to school, and struggling with work which are all the things I am so passionate about,' she shared.

'You are the only person that would believe me and understand what I was going through.'
