Natasha Kaplinsky won the first series of Strictly Come Dancing
Newsreader Natasha Kaplinsky has given birth to a boy, but has not yet named the child.
The birth was announced on the evening Five News bulletin, which Kaplinsky, 36, presented before she took maternity leave last month.
Her husband Justin Bower, whom she married after a whirlwind romance in 2005, said: "We're absolutely thrilled."
A spokeswoman for the presenter said: "Mother and baby are doing fine."
Five News said: "Her colleagues here at Five News are delighted too - and we've sent our best wishes."
The former Strictly Come Dancing star made her debut as the face of Five's news coverage in February, in a deal reported to be worth £1 million a year.
Kaplinsky's first broadcast attracted one million viewers - almost double the usual audience.
The move to Five marked the latest in a career that has seen Kaplinsky make an almost complete tour of the British news networks.
She first started in broadcast when she was selected to present the early morning news bulletins at ITV Meridian in 1997.
She has also worked for ITV London, Sky News and BBC Breakfast before moving to the station's Six O'Clock News.
British newsreader Natasha Kaplinsky gave birth to a baby boy earlier this morning at around 08:30 BST. She had been on maternity leave since August 21. Kaplinsky had only been working with Five News just over a month when she announced she was pregnant. Her husband of three years, investment banker Justin Bower announced "We're absolutely thrilled."

Kaplinsky first started to work for the BBC in 2002 after a two year tenure with Sky News. She started on the BBC Breakfast show but later moved onto the BBC Six O'Clock News and later became only the third woman to present the BBC Ten O'Clock News. She left the BBC in October 2007.  She also spent a short time with ITV News.

Five News released a statement saying "Her colleagues here at Five News are delighted too - and we've sent our best wishes." They also said both Kaplinsky and the baby are doing fine.
