Keira Maguire flashes some serious sideboob in a VERY plunging sheer lace bodysuit as she poses up a storm at Australian Grand Prix

She admitted she fights with 'everyone' and is at the centre of much of the drama on Bachelor In Paradise, which debuts this Sunday.

And Keira Maguire stole the limelight once again on Saturday, as she posed

up a storm at the Australian Formula One Grand Prix at Albert Park in Melbourne.

The plastic-surgery loving Bachelor star, 31, ensured all eyes were on her as she showed off her generous cleavage in a plunging sheer lace bodysuit.

She's got a lot of front! Keira Maguire flashed some serious sideboob in plunging sheer lace bodysuit as she posed up a storm at Australian Grand Prix on Saturday.

Showcasing every inch of her toned physique, she teamed the garment with skintight blue ripped jeans.

Injecting a dose of glamour into the look, the reality star rocked a Gucci monogrammed chain-trim bag and drew further attention to her decolletage with a gold pendant necklace.
