Regina "Reggie" Bird (now Reggie Sorensen) was a contestant and winner of Big Brother 2003 Australia. Small in stature with an unusual nasal intonation, she earned public admiration with her down-to-earth charm, strong work ethic, and naivety. Reggie was widely tipped to win Big Brother from early in the series and won with 72% of the final vote, the biggest margin in a Big Brother Finale to date. She is the first female winner of the Australian series. "Go Reggie" bumper stickers were a big hit in Tasmania.
After her win, Reggie signed up with manager Harry M. Miller and filmed a pilot for a TV show which never made it to air. Later she appeared as a contestant on 2005 Nine Network celebrity skating competition series Skating on Thin Ice. From December 2004 to May 2005 she worked for airline Virgin Blue as a flight attendant – her "dream job" – although she resigned claiming she had been bullied by her colleagues. In 2005, Bird lost $40,000 to a conman.
She spent some time residing in Sydney and later Melbourne. She now lives in Queensland. She gave birth to her first child, a daughter – Mia Regina Sorensen – with her second husband, Dale Sorensen. In 2008 she underwent emergency surgery arising from an ectopic pregnancy and was also declared legally blind after having been diagnosed with a degenerative eye condition.
Reggie was involved in the week 12 task on season 9 of Big Brother Australia in 2012 when she entered the house to try to get the current housemates at the time to fail their weekly task which was to ignore everyone who enters the house that isn't a housemate.
