The supermodel risked a major wardrobe malfunction as she enthusiastically celebrated during the game between the Los Angeles Lakers and the New York Knicks.

Wearing her dark tresses down, the 21-year-old’s incredible figure was impossible to miss as she stuck to the legs or chest rule and pulled it off with very sexy results.

Bella exposed serious cleavage as she sat court-side with singer Justine Skye in a daringly, low-cut top.

The beauty’s assets took centre-stage in the plunging white top, complete with a V-neckline, tight fit and long sleeves.

At one point Bella was even seen gripping her chest after teaming her ruched get-up with high-waisted jeans.

The Victoria’s Secret Angel also opted for trainers, a large gold pendant, hooped earrings and lashings of eye make-up.

It appeared to be a busy night for Bella who later tweeted her 940,000 Twitter followers gushing about a gig.

She wrote: “Yo @sza was so completely next level tonight. That voice + her presence on stage is so magical. If you ever get the chance to see her perform - Do it. So much love.”(sic)

Bella’s outing came just hours after she was spotted posing up a storm at a Brooklyn diner.

She once again highlighted her décolletage by going braless in a striped, off-the-shoulder top, which looked close to slipping down.
