AS three new heads were placed on the chopping block, an intruder entered the Big Brother house last night.
Ava, 29, is a singer songwriter from Melbourne who is set to shake things up this week as she brings the number of people in the house back to 12.
She stealthily entered the house via the Captain's Quarters at the end of last night's nominations show, during which Estelle, Ray and Angie received the most points for eviction from their fellow housemates.

Viewers will watch as the housemates meet Ava for the first time tonight.
