Tori Spelling and Dean McDermott welcome their fifth child

Tori Spelling and Dean McDermott have welcomed their fifth child into the world.

Actress Tori, 43, announced the happy news on social media, tweeting a black and white picture of the little one’s hands to her 1.08 million followers and writing: ‘We are so excited to announce the birth of the newest member of the McDermott family!’

She also revealed the baby name that they’d chosen for the new arrival: ‘Please join us in welcoming Beau Dean McDermott.’

‘We are over the moon in love with baby Beau. He is a true blessing and his brothers and sisters were overjoyed to meet him! We are all truly grateful for our big beautiful and healthy family,’ she continued to PEOPLE magazine.

The couple are already parents to Liam, aged 9, Stella, aged 8, Hattie, aged 5, and 4-year-old Finn, whilst Dean also has an 18-year-old son, Jack, from a previous relationship.

Tori announced that she was expecting again back in October 2016, telling PEOPLE that the pregnancy was a total surprise.

‘But we always wanted a big family,’ she added. ‘I’m really excited.’

‘Dean was saying, “We just got Finn out of diapers; I thought we were in the clear!”‘

‘For the first time this year, they’re all in school. So it’s like, wow. We’re basically starting over.’

Tori and Dean announced that they knew they were having a son in December of the same year, with a video of a Christmas tree adorned with blue ornaments.

‘With Liam and Stella, we found out at the doctor’s office. Hattie and Finn we didn’t find out until they were born. So this is the first reveal,’ Tori explained.

‘We really wanted to do it with the kids because they were so excited and we wanted to do it as a family.’

‘This baby happened at the best time. Nothing is ever perfect, but I’m so madly in love with my husband and with our kids. The idea of adding to that is such a blessing.’
