The couple are already parents to daughter Wynter, one, and are expecting baby number two in five months time.
Kenzie's rep confirmed his happy news to us this morning (4 June), adding that both the 5th Story star and Frankie are "thrilled". Congrats!
Earlier this year, Kenzie admitted to Reveal that he and hairdresser Frankie wanted to have more children.
Kenzie said: "I want to have another baby soon. I actually want three or four children. My parents are from big families and I'd like a massive one too!"
The next few months are going to be seriously busy for both Kenzie and Frankie. Their baby is due right when 5th Story are on the 'Big Reunion Boy Bands Tour', Frankie has recently opened her own salon for hair-loss sufferers and Kenzie has just launched his own clothing range. Phew!
Kenzie's line, called Box Menswear, features polo shirts, hoodies, shorts and even undies, and is available online now.
Not only did he pick out the pieces for his collection, Kenzie has also modelled them and can be seen on the shoot in the video below too. Swit swoo!
