Miranda Kerr's security guard has been stabbed in the eye trying to fight off an intruder at her Malibu home.

The man was attacked by an intruder trying to climb a fence to gain access to the property, where the model lives with her five-year-old son Flynn, at 11.10am on Friday.

Her security guard shot the intruder several times including once in the head.

Both are receiving treatment in a Los Angeles hospital. The security guard was airlifted from the scene by the Los Angeles County Sheriff's Department.

He was stabbed below the eye but was seen walking on to the LA County Sheriff's Department chopper unaided after the attack.

He shot the intruder four times, LA County Sheriff's Office told DailyMail.com on Friday afternoon.

Police could not confirm whether there was anyone else in the property at the time. The intruder, the spokesman added, will face charges.

Australian morning show Sunrise reports the man may have been homeless.

The intruder was airlifted separately to a trauma center. Kerr, 33, was not home when Friday's disturbance occurred.

Her fiancé, Snapchat CEO Evan Spiegel, recently purchased a sprawling mansion for the pair in Brentwood, Los Angeles.

Earlier this year, she invited Harper's Bazaar Australia into her 1960s ranch in northern Malibu.

The Australian model bought the property in 2014 following her split from ex-husband Orlando Bloom.
It comes just a week after Kim Kardashian was held at gunpoint and robbed in her luxury apartment in Paris.
Kerr was also in the city at the time to attend Paris Fashion Week. Her representatives did not comment on the incident on Friday.

She has been silent on social media for a week but was spotted leaving Soho House in Malibu on Sunday with friends.
