Big Brother's lesbian love scandal

Evicted Big Brother contestant Tully Smyth has admitted she cheated on her girlfriend Tahlia while inside the house.

The 25-year-old was evicted from the Nine Network reality TV show on Monday night.

After little sleep, the former model put on a brave face and answered questions about her relationship with housemate Drew during a number of radio interviews on Tuesday morning.

The pair were regularly captured on camera kissing and cuddling while in the house. They even professed their love for each other on many occasions.

Their close relationship was attacked on social media and Tully has now conceded her conduct could have been considered cheating.

"Thinking is cheating in my books so yes, I guess it is," she told Southern Cross Austereo.

"I'm not going to brush that off."

The social media strategist says she hasn't been able to speak to Tahlia since her eviction.

"I haven't had a chance to speak to Tahlia since last night," she said.

"Once it's all calmed down and the dust has settled, I'd definitely speak to her properly about it.

"I think I will definitely have to change my relationship status (on Facebook) to 'it's complicated', now."

The former housemate also played down her relationship with Drew, saying the show's editing added to the story.

"You guys only see a snippet," she said.

"Everyone loves a love story. We were house husband and wife, we bickered like husband and wife.

"I don't even know if Drew and I (would) get along in the outside world. We just have to wait and see."

For her part, Tahlia said she would be avoiding Twitter in the wash up.

"Thanks a million to everyone being lovely, but I am staying off twitterland for the next few days."
