Matt Smith reportedly has a new girlfriend. The 'Doctor Who' star - whose last serious relationship was with actress Lily James - is reportedly dating investment banker Caroline Brady, 30, who is a sister of actress Millie Brady. A source told The Mail On Sunday's Talk Of The Town column: "Last month, Millieâs friends were saying excitedly that her sister is seeing Matt Smith." Caroline previously dated Bryan Ferryâs eldest son Tara, while Matt, 38, split from Lily in December 2019 after a five-year romance. The couple were believed to have briefly rekindled their romance in spring 2020 during the Covid-19 lockdown.
