Outrageous Fortune's Antonia Prebble welcomes first baby with adorable photo

Kiwi actress Antonia Prebble has announced the arrival of her first child, a baby boy with fiance and Westside costar Dan Musgrove. 

The Outrageous Fortune star shared the news with a touching image of her baby's hand wrapped around a finger. 

"Dan and I are so delighted to share that our beautiful boy is now with us in the world," she captioned the image. 

"Freddie John Musgrove was born just over a week ago and is adjusting really well to his new digs outside my belly - and Dan and I are completely besotted." 

Earlier this year, Prebble and Musgrove announced they were expecting their first child in an interview with Woman's Day. 

"Having children was something I'd always imagined would be part of my life, but until recently, it always felt like it was far off in the future," she said.

"Then suddenly, for both of us, it felt right. We were engaged, planning a future together and talking about starting a family. We were elated."

The 35-year-old rose to fame as a teen with her role as Loretta on Outrageous Fortune. She's recently been filming the latest season of the show's prequel series, Westside, where she plays the show's lead, Rita.
