Model-turned-actress Kelly Brook said that she turned into a “monster” due to hormones when she became pregnant in 2011, and even thought ending the relationship with her boyfriend.

The TV star was shocked when she found out that she was pregnant with her first child with Thom Evans, a former rugby star, just weeks after they started seeing each other.

Brook suffered a miscarriage after five months, and said her pregnancy had been difficult.

"It's been tough. We had our fair share of trials and tribulations with my pregnancy. My hormones were all over the place and I didn't know if I wanted to be in a relationship because we'd just met,” Brook told Glamour magazine.

Brook said that having a family was the “last thing” she thought of at the time. All of a sudden she found herself with someone she didn’t “know that well” and she was pregnant.

She admitted that it was a “beautiful thing” but also a “really scary thing”, and that her and Evans probably saw each other at their worst.

"I was a monster at some points, because your hormones are so all over the place. It's bad enough when women have that time of the month, let alone going through that. I guess we're kind of lucky that we got to know each other on that level so quickly," Brook said.
