The 30-year-old is currently on holiday with her fiancé Ryan Thomas and their son Roman.
Just last month the pair revealed that they were expecting their second baby together as Lucy posted: "Here we go again."
Lucy Mecklenburgh showed off her growing baby bump in a chic blue bikini while posing alongside her eldest. The family is staying at the St Regis Hotel on Saadiyat Island as they enjoy the winter sun.
They also paid a visit to the Emirates Park zoo where they fed giraffes.
Gushing about the break, Rylan said traveling long distance with a toddler had been fine until Lucy made parenting fail in the hotel room.
The former Jason Grimshaw actor said his wife-to-be accidentally turned on every light in their suite saying: "Roman started screaming!"
Lucy gave birth to Roman, who is now 19 months old, last year. She recently opened up about terrifying health care that saw her son end up in hospital. The mum found her baby boy blue in her cot back in September.
Little Roman was taken to Basildon Hospital near their Essex home and was then transferred to London's St Mary’s Hospital where he was then put on a ventilator. They found that the illness was viral and he is now doing well but has to now use an inhaler twice a day to help his breathing.
As well as caring for son Roman and gearing up for baby number two, Lucy and Roman have also been in talks surrounding their upcoming wedding.
The pair have decided to put the big day on hold to have both their children with them. A source told a magazine: "Lucy isn't too concerned about wedding plans but would like to get her figure back after her second child is born."
They went on to say that a summer 2022 wedding is off the cards because Lucy would like to wait until her children can be more involved in the wedding.
They added: "Lucy is really glad the babies will be close in age and loves that if she has a girl she'll have an older brother in Roman to watch over her."
