Dumped by Who: Daisy Lowe and Matt Smith split up after actor calls time on their 18-month long relationship



They've been apart for most of the summer due to work commitments.



However it appears the prospect of long-term commitment that appears to have caused the breakdown of Matt Smith and Daisy Lowe's relationship.



The Doctor Who actor, 29, is reported to have become 'uncomfortable' at the mention of marriage and called time on their 18-month-long romance.

Matt, who plays Doctor Who in the hit BBC sci-fi series, is said to have become increasingly uneasy about settling down and tying the knot with the 22-year-old.



A friend is said to have claimed in The Sun newspaper: 'Whenever engagement and marriage was mentioned he was uncomfortable. He's still a young man and the thought of being tied down was a lot to digest.'

They also said: 'This has come as a surprise to everyone. It was thought they'd be together for a really long time because they were so into each other.
