Scarlett, 27, is being lured to return as Black Widow in the superhero sequel. 
 
 The £13million fee tops Angelina Jolie’s £12.2million for The Tourist. 
 
 Movie bosses want Scarlett to sign after Avengers Assemble grossed £936million — the third highest in history. 
 
 A source said: “Scarlett is the hottest star in Hollywood and her inclusion in the sequel is a must. 
 
 “Producers think that as the only lead woman in the film male fans have found her a key ingredient — both for sex and story appeal. She is loved by critics too. 
 
 “This says, ‘We value you’. Everyone is confident she’ll sign and be ready for 2013 filming.” 
 
 Robert Downey Jr, Chris Hemsworth and Jeremy Renner are also to get 50 per cent pay rises.

 Scarlett Johansson isn’t just the sexiest woman in Hollywood, she’s also the most bankable. 
 
 The curvy superstar is set to pocket a record-breaking $20 million to reprise her comic-book heroine role in an “Avengers” sequel, according to a published report yesterday. 
 
 Her Black Widow was such a hit, “Avengers” producers are willing to break the bank, Britain’s Sun reported. 
 
 The payday would top the standing record for an actress — $19 million reportedly earned by Angelina Jolie for “The Tourist.” 
 
 Superheroes are all the rage in Tinseltown nowadays, as “The Amazing Spider-Man” climbed to the top of the box office this weekend with $65 million in ticket sales. It has raked in $140 million since opening Wednesday. 
 
 Last week’s top finisher “Ted” — about a slacker and his hard-partying teddy bear — finished second, with $32.6 million in sales. 
 
 In third place was Pixar’s “Brave,” with $20.1 million in domestic sales.
– Scarlett Johansson's sexy curves and, uh, epic acting skills are worth no less than $20 million, the New York Post reports. Producers of an Avengers sequel are prepared to sign the eye-popping paycheck so she'll reprise her role as Black Widow when filming starts next year. “Scarlett is the hottest star in Hollywood and her inclusion in the sequel is a must," a source tells the Sun. "Producers think that as the only lead woman in the film male fans have found her a key ingredient." Johansson's fee takes second only to Julia Roberts' $25 million for Mona Lisa Smile, a payment reported by Forbes.
