Newman-raised electrician George Baramily has attracted widespread attention on the internet since entering the Big Brother house on Tuesday.
Viewers were told that Baramily or 21-year-old male model Ryan Buckingham was the reality show's multi-millionaire, but the "secret" was quickly uncovered after images surfaced on Twitter of Baramily in Australian Property Investor magazine featured as a "young millionaire".
According to the article published in the magazine's June edition, Baramily bought his first investment property six years ago, which has seen him go on to obtain $3.722 million equity in a property portfolio worth $6.75 million.
Baramily, 25 - who works for BHP Billiton - was also reported to have had a tough childhood, having shared a poky studio apartment with his sister and mother for nearly three years as they waited for government housing.
As soon as some viewers realised Baramily's secret, they took to Twitter to express their disappointment.
"Just found out George for #bbau is the multi-millionaire because he was in a magazine for being one a while back... nice secret Big Brother!" one wrote, while another tweeted "Kinda disappointing that we all know George is the millionaire on Big Brother... But oh well..."
When Nine's rebooted version of the former Ten show launched on Monday, Big Brother revealed to the female contestants that in order to avoid eviction, they must correctly pinpoint which of the seven secrets belonged to the seven male housemates, including who is a millionaire, who is a genius and who was a juvenile offender.
Though viewers are now aware of Baramily's millionaire status, his dreadlocked looks and laid-back attitude could have his fellow housemates fooled into thinking he is anything but.
The final two housemates - Queensland vet Ray, 25, and Victorian accounts manager Benjamin, 32 - entered the house last night.
Meanwhile, Big Brother attracted an average of 1.327 million viewers nationally on Tuesday - about 300,000 fewer than Monday's launch episode - making it the second most-watched show of the night after Seven News.
Nine's double episode premiere of *Charlie Sheen *'s new comedy series, Anger Management, took out the nation's fifth and sixth spots, pulling 1.112 million and 1.106 million viewers respectively.
In Perth, Seven News won the night, attracting 212,000 viewers, followed by Today Tonight with 166,000 and Big Brother with 150,000 viewers.
Big Brother continues today at 7pm on Nine/WIN.
