Will Lucy Speed character Natalie return to EastEnders?
Lucy Speed’s big break was at the age of 17, when she won the role of Natalie Price in EastEnders.
Natalie was the long suffering best friend of Bianca Jackson, but her affair with Ricky ending his relationship with Bianca.
She chose to leave the soap after a year due to feeling overwhelmed and unprepared for all the attention she received from being in such a high-profile show.
She said at the time: “I was very frightened by it quite frankly and certainly unprepared for it.
“I didn’t like all the attention that came with being on such a high-profile show at all.
“It simply wasn’t what I signed up for in the first place – all that craziness.
“I was very young and extremely shy, so it all became a huge difficulty for me.
“I honoured my initial one-year contract and then moved on.”
However, in 1999, she reprised the role of Natalie to “pay the mortgage” and became a love interest for Barry Evans, eventually marrying him and having his son Jack.
Her storylines included a rocky marriage to Barry and almost sleeping with her brother-in-law.
She rekindled her affair with Ricky, had a relationship with Paul Trueman and desperately tried to get Janine Butcher arrested for murdering Barry.
She left the soap once again in 2004 after five years, explaining the scripts weren’t keeping her busy enough.
Lucy has previously said she would consider returning to Walford.
