Actress Jo Joyner fluffed her lines in a live section of EastEnders tonight when she confused the name of a character with the man playing him.
Joyner, who plays Tanya Branning in the long-running soap, asked Jane Beale, played by Laurie Brett: "How's Adam?"
Brett looked puzzled - which was not surprising, as Joyner was supposed to be asking after Ian Beale, Jane's husband in the show, but instead said Adam. Ian is played by Adam Woodyatt.
The incident led to much amusement on Twitter. One comment, apparently referring to Ian Beale's role as a suspect in the murder of his daughter Lucy, said: "Adams fine love, it's Ian you need to be concerned about."
There was support as well, with one post saying: "You did good @dollyjoyner what can i say everyone makes mistakes live or not."

And the actress tweeted: "You never answered me @LauriebrettX how is @AdamWoodyatt ?... #leastyouknowitslive #gutted"
The murder is due to be solved tomorrow, but viewers were little wiser tonight, though Beale's son Peter told his father and Jane at the end: "Lucy was killed in this house, it was one of you."
However there are bound to be more twists and turns before the revelation of how she came to die.
Meanwhile, Jake Wood also caused consternation for Eastenders fans when he appeared to fluff his lines during a live scene in the final moments.
One scene showed the character Lauren Branning depart in a taxi, claiming she knew who Lucy Beale's killer was.
However, in a later live scene Wood's character Max Branning, when speaking to his daughter Abi, said either "Lauren knows WHO killed Lucy" or "Lauren knows YOU killed Lucy".

The confusion sent fans into meltdown as they wrestled with the meaning of what he was saying. They promptly took to Twitter in search of clarity.
Wood then took to Twitter himself to clear up the matter with the message, "For the benefit of the Internet and mankind in general please RT YOU. Thank YOU (see what I did there) #EELive #justthebeginning."
Displaying a healthy sense of humour he then re-tweeted fans who slagged him off for breaking the internet more effectively than Kim Kardashian's bum display for Paper magazine.
However, it's not the first time Jake has had a live mishap. During a previous live episode screened in 2010, he was seen sticking his hand down his throat on camera as his character was supposed to vomit following the death of his son Bradley (video below).
