Our favourite photo had to be the one of Blake in his mini flat cap!
We've been lucky enough to have seen numerous photos of Blake settling into family life over the last few weeks, most recently when Rochelle shared a photo of her son's very impressive nursery, featuring elephant bedside lamps, candles in the shape of jaguars, tiger printed cushion covers and a fabulous leopard print carpet and changing mat.
Rochelle and Marvin welcomed little Blake on Friday 9 October, revealing the joyous news on Instagram.
"Blake Hampton Humes. On Friday morning at 8.44am our boy arrived to flip the switch on 2020. I didn't think I'd ever fall in love with another man but this guy has stolen my whole heart and we've been in a love bubble ever since..." Rochelle wrote at the time.
Marvin echoed his wife's sentiment, writing: "My son! My son!!! Feels so weird but amazing saying that. Blake Hampton Humes was born on Friday weighing 8 pounds 2 ounces. Rochelle is a superwoman..family complete."
