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 Ł1 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.
