The Australian television personality and comedian, who is best known for hosting The Project alongside Carrie Bickmore and Dave Hughes, asked Sarah Krasnostein to marry him on Sunday.
According to the Herald Sun, Krasnostein showed off her new engagement ring at the GQ Awards in Sydney last night.
Pickering, Bickmore and Hughes recently had The Project renamed and extended by 30 minutes when George Negus's current affairs show was axed by Channel Ten.
Former Home and Away actress Sharni Vinson attended the GQ Awards with her new boyfriend, Twilight star Kellan Lutz. He is believed to be meeting her family in Cronulla during their visit to Australia from the US.
Lutz was swamped by female fans on the red carpet, to which Vinson said: "I don't think I would say I'm used to it - but it's familiar!"
Rachael Taylor also made a public appearance at the event in the wake of ex-boyfriend Matthew Newton telling all about his assault on her on A Current Affair earlier this week. She is now dating Josh Lawson.
