Celebrity mums welcoming children later in life is becoming increasingly more common, with many opting to spend their 20s and 30s child-free. While having a baby over the age of 35 is still medically referred to as a 'geriatric' pregnancy, many big names in showbiz have had happy and healthy pregnancies and births later in life. From TV presenters to reality stars, a number of A-list women have welcomed a baby in their 40s and even 50s.
