David Tennant 'to become a father'

David Tennant and partner Georgia Moffett are reportedly expecting their first child together.

The pair, who are said to be engaged, have been keeping the news a secret and will welcome the new arrival in the spring, The Sun reports.

The former Doctor Who star met Moffett - real-life daughter of Fifth Doctor Peter Davison - when she made an appearance on the show in 2008. The actress already has an 8-year-old son, Tyler.

A source said: "David is thrilled, though slightly worried having a baby with Georgia will break the space time continuum because of their Doctor Who connections. David gets along brilliantly with Tyler and can't wait for the baby."
