The former Dancing With The Stars winner revealed the happy news by posting a family photo on Instagram on Wednesday (04Nov15), in which the couple's three-year-old daughter, Ava Grace, holds up a sign which reads "And then there were five", while son Beckett Thomas, 18 months, places his hands on a placard with the phrase "Big Brother" written on it.

"This is definitely the last one... probably," Rycroft wrote in a caption. "#partyoffive #babyonboard #maybethisonewilllooklikeme."

The mum-to-be, who also appeared on dating show The Bachelor in 2009, wed Strickland later that same year after a six-month engagement.
