It's been almost two decades since Big Brother first hit our screens in 2001.

Back then, Australians gathered in their lounge rooms to watch a group of strangers live, eat, share secrets, and even find love on national TV.

Watch: Housemates face their fears on the latest season of Big Brother. Post continues below.

Now, 19 years on, the current season ofBig Brothercertainly looks different. But despite the change to the show's format and the usual breed of housemates, two contestants have still managed to find a romantic connection.

Yep, we're talking about Chad Hurst and Sophie Budack, who have continued to grow closer after entering the house as latecomers.

In fact, the pair even joked about getting engaged during last Sunday's episode.

"Chad last night, I don’t know if you recall this Chad, he asked for my hand in marriage," Sophie told the rest of the housemates.

"Say what? This 17-day romance is peaking!" fellow contestant Shane Vincent responded.

"You’re all invited to the wedding!" Sophie joked.

Pete and Christina (Season 1).

Pete Timbs and Christina Davis were the very first contestants to start dating in theBig Brotherhouse back in season one. They were also the couple behind the infamous "dancing doona" incident... but we won't get into that.

Despite their romance on the show, the pair decided to go their separate ways shortly afterwards. Pete is now married to his wife Camilla, who he shares two girls with, and runs a cafe in Byron Bay. Speaking onThe Morning Showearlier this month, Pete shared that he still keeps in touch with fellow housemates Blair McDonough, Ben Williams, Johnnie Cass and Jemma Gawned.

Meanwhile, Christina has found success in stand-up comedy, having performed at the Melbourne International Comedy Festival and Edinburgh Fringe Festival.
