Reality star Peter Andre welcomed his first child with girlfriend Emily MacDonagh.

The 40-year-old Mysterious Girl hitmaker confirmed that his partner, 23, had given birth to a "beautiful baby girl" in a post on his channel.

He wrote: "Now that I have had the opportunity to tell Junior and Pringles, we are very happy to announce the safe arrival of our beautiful baby girl.

"We are extremely thrilled and mum and bubba are doing fine."

He added: "We are looking forward to a nice quiet couple of weeks getting to know our baby. Thanks to everyone at Musgrove Park Hospital."

His page was quickly inundated with congratulatory messages from fans and fellow celebrities.

The announcement came just hours after the Twitterphere was rife with rumours that the couple's bundle of joy had entered the world at a hospital in Somerset.

One fan tweeted: "Peter Andre is in the hospital I work at with Emily and his baby daughter omg."

Andre is already dad to daughter Princess and son Junior with ex-wife Katie Price.
