ITV's hit period drama Downton Abbey will return to our screens later this year, and in the meantime we've been given plenty of tidbits about what we can expect from season four, and our latest news story from the set of the show is that we have two new, very young stars joining the cast. Cumbria-born twins Logan and Cole Weston have been picked to share the role of Baby George, the son of Lady Mary (Michelle Dockery) and her late husband Matthew, who was written out of the show during last years' Christmas finale.

The twins, who hail from Meathop, near Grange-over-Sands, Cumbria, will appear throughout the series as the youngest addition to the series, with filming for the new season coming to an end in the last few weeks. As reported by the BBC, the twins were given the all-star treatment on the set, and were treated with their own trailer and a limitless supply of sweets, milk and attention during the filming for the upcoming season. The twins make up just one of the many new stars due to join up with the Crawley family, including Hollywood star Paul Giamatti, James Fox and Gary Carr, who will star as the first black actor to appear on the show.

Giamatti will only feature in the special Christmas day episode, in which he will play Lady Cora's (Elizabeth McGovern) unpredictable brother, with her outspoken mother (Shirley Maclaine) also due to return to the series. Dame Kiri Te Kanawa is also one of the guest star due to appear in the fourth season of the hit series, playing opera singer Dame Nellie Melba mid-way through the season.

Hugh Bonneville
Hugh Bonneville has committed himself to the show by signing a new deal with producers

With his fictional sons making their way on to the show in the next season, the departure of Dan Stevens at the end of the last episode is an unpleasantry that the show's producers won't want to happen again. To combat another potential exodus from the show, the series' producers have recently handed new deals to stars Hugh Bonneville, Elizabeth McGovern and more, with some of the major stars set to earn as up to £1,000,000 in their new three year deals.

Season four of Downton Abbey will air in September, with the season this time set in 1922.
