We're used to seeing Terri Irwin in her iconic khaki uniform with her signature thick blonde fringe, but shock photos from 2002 have just been released and Terri looks like a total bombshell in the shots.
According to The Hits, friends told New Idea magazine that Terri stuck with her look for decades because she wanted to be taken seriously as a conservationist.
But judging by these old pics, she decided to go for a whole new, sexy look.
Terri also recently opened up about her plans to have a third child with her late husband Steve.
While walking the carpet at the annual Steve Irwin Gala Dinner in Los Angeles over the weekend, the 52-year-old revealed she had suggested having a third child prior to Steve's tragic death in 2006.
'I said to Steve, 'Let's have a third',' Terri told E! News.
'And he said, 'You have a girl and you have a boy. What are you hoping for?''
'Steve said to me how excited he was when Bindi was born,' Terri added.
'He said, 'Do you think we could have a boy?' And then Robert was born, and they're perfect. They're easy kids; they're wonderful to me; they're such a help.'
Terri walked the carpet alongside 18-year-old Bindi and also spoke about their sweet relationship.
'I think the secret is love at first sight,' Terri said.
'Some people don't believe in it, and then you have a baby and fall in love with this person the way you never knew you could love somebody.'
