London, March 14 (IANS) Unlucky in love so far, David Schwimmer's relationship this time with his British girlfriend has turned serious as the former 'Friends' star is reportedly planning to propose.

The 43-year-old actor-director has been dating Zoe Buckman since 2007 when they met while she was working as a waitress at a London restaurant and he was in the city filming 'Run Fatboy Run'.

Contactmusic.com reports that Buckman, 23, is now said to be living with Schwimmer in the US and he's reportedly planning to make their relationship official.

'David is smitten with Zoe and says she is the one. Things have moved very fast. He wanted to see how they got along living together and it has been a big success. He wants to ask Zoe to marry him, it's just a case of timing,' said a source.

'He has been living with Zoe in Chicago recently working on a stage show called 'Trust' and they will probably make an announcement when they come back to Los Angeles. We are all bracing ourselves for good news,' the source added.

Schwimmer has been previously linked to stars like Natalie Imbruglia and his sitcom co-star Jennifer Aniston too for a short while.
