Emma was previously married to lawyer Nigel Stoat.
The pair tied the knot in 2002 but split in 2005.
In 2007, reports suggested that Emma was in a relationship with ex-EastEnders star Joel Beckett.
A few years ago fellow EastEnders star Jamie Borthwick, who plays Jay Brown in the soap, told the TV Times he had a crush on Emma since he was 14.
