A pregnant mum was stunned when a baby orangutan repeatedly kissed her bump through the glass at a zoo.

Naomi Davies, 34, was visiting Twycross Zoo with her fiancé Ben Billingham, 40, when they stopped by the monkey enclosure.

To her amazement, a baby orangutan climbed on an adult monkey's back and lunged for the glass, to repeatedly kissed her pregnant stomach.

Support worker Ben started filming the special moment as Naomi, who was four months pregnant at the time.

Nursing assistant Naomi, from Gloucester, said: "It was really lovely!

"We'd been to that zoo once before and absolutely loved it, but this trip was actually the first time I'd seen an orangutan in a zoo.

"The mum orangutan brought her baby over to the glass and they were watching us.

"My partner Ben said to try showing her my baby bump as he'd seen interactions from orangutans before."
