Frankie Bridge is experiencing "horrific" morning sickness and as a result hasn't left her bed for days.

Frankie Bridge "hasn't left her bed" for days.

The Saturdays singer - who already has 14-month-old son Parker with husband Wayne Bridge - is thrilled to be expecting her second child but is battling severe morning sickness that has seen her have to pull out of the 'Strictly Come Dancing' tour.

She said: "I'm obviously over the moon but the sickness is horrific.

"I haven't been able to leave my bed for days and my doctor's instructed me to rest and not exercise, so dancing was completely out of the question. I'm hoping it will pass quickly so I can continue to enjoy my pregnancy and get back to work."

The 25-year-old star - who is still in her first trimester but announced her pregnancy so fans would understand why she wouldn't be on the dancing show's tour - can't wait to welcome another addition to her and Wayne's family.

She added to OK! magazine: "I absolutely love being a mum and having Parker was the best thing that ever happened to me.

"The thought of another addition to our little family is the most exciting thing ever."
