She's currently expecting her second child but radio presenter Fifi Box is still hard at work in the studio.
And during a live broadcast of her Fox FM breakfast show Fifi, Fev & Byron, the pregnant star became the focus of a playful prank by her co-host Brendan Fevola.
Enlisting the help of Fifi's daughter Trixie, the former AFL pro played a pre-recorded message of the five-year-old saying "I love you mummy" on air - prompting his colleague to burst into tears in the middle of the programme.

The practical joke came about after Brendan discovered how difficult it was to make Fifi cry.
The 42-year-old sobbed almost instantly when she heard little Trixie - who she shares with ex Grant Kenny - declare what she likes most about her mother.
"I like how you cuddle me. I like it when you take me places.
"Love you mummy. Bye bye," Trixie said.
Seeing Fifi's tears, Brendan triumphantly declared "Got her!" before posting a video of the moment to Fox FM's Instagram account.
In February, Fifi announced she was pregnant with her second second child via IVF.
The media personality revealed she used an anonymous donor and admitted she was filled with "pue joy" over the news.
