Katie Lamb and Martene Pearman are expecting their first child together, almost a year after they announced their engagement.
The Perth-based radio host, 27, shared the exciting news on Sunday by posting a precious clip of her celebrating with her AFLW West Coast Eagles coach fiancée.
The pair are seen standing in a backyard holding small fireworks which they set off amid a cloud of pink smoke – suggesting they are having a daughter.
The couple then embraced each other and yelped in laughter as they celebrated the incredible news.
The Triple M star captioned the clip: ‘A little Lamb is cooking! Baby Lamb is in the oven.’
Many of their celebrity friends took to the comment section to congratulate the happy couple.

‘OMG YES MY HEART!!!!!’ gushed AFLW WAG Sophie Cachia.
‘Oh you guys. The happiness in this video is joyous to watch,’ added The Block veterans Luke and Jasmin.
In April, the pair confirmed their engagement with Katie revealing she popped the question on Easter Saturday.
At a beach in Eagle Bay in Western Australia’s southwest, Katie pulled off what she called ‘the biggest blind side of all time’, presenting a ring to Pearman as their pet dog kicked up a sandy fuss.
‘Our three-year-old cavoodle, Reggie, managed to steal the moment at one stage, frantically digging and flicking sand all over the ring but we wouldn’t have had it any other way,’ Lamb said.
‘We celebrated with a delicious lunch and then had a bunch of friends surprise us at Aravina Estate.
‘Were overwhelmed with so much love and support from friends, family and Insta besties.
‘Thank you so much to everyone who made us feel so special.

‘Now, I need to sleep for a year. Wake me up when it’s our wedding.’
In her post, Lamb explained the proposal didn’t quite go as planned.
‘This morning we walked to our favourite spot in Eagle Bay and for the first time ever, [Martene] decided to do 10 minutes of bloody ‘breathing exercises’ on a gigantic rock. That wasn’t part of the plan,’ she wrote in her caption.
‘Once I convinced her to come down and after Reggie stopped frantically flicking sand all over us during the moment, we locked her in.’
The heartwarming and candid moment was captured on video and included in Lamb’s post.
She hosts Triple M’s Rush Hour with Embers and Katie show, which is owned by ASX-listed radio giant Southern Cross Austereo.
The show is also on the LiSTNR app, which houses SCA’s radio, podcasts, music and news.
