Salma Hayek had viewers on tenterhooks when she candidly recounted the stress of engaging in complex detective work to find out if her husband was having an affair.

The Hollywood star spoke of how she came to think her husband François-Henri Pinault, who is a French billionaire, was taking part in some untoward deeds with a woman named Elena last week.

Launching into an anecdote on The Tonight Show with Jimmy Fallon, Hayek said: “So, about a year ago he [her husband] said, ‘you know what guys, I’m going to get a dialect coach and I’m going to get rid of the accent before you who has been living in the States for like 67 years’, referring to me".

“He never mentioned it again so I thought he didn’t do it,” the actor continued.

“A couple of days ago I’m texting someone and I see his phone, and there’s this message.”

Donning her very best and most seductive “other woman” voice, Hayek then proceeded to impersonate the text, saying: “Hi, this is Elena, if you want to improve your English, you have to practice, do you want to practice now?”

Hayek, who was born in Coatzacoalcos, Veracruz in Mexico, then confessed: “I’m Mexican, you know it doesn’t go well”.

“So I was so furious and I said well obviously she’s desperate, he’s not calling her you know, should I say something? I trust him, I won’t say anything.

“Four hours later, we’re eating, I’m cool, I go hi, baby and everything is okay and then I go, who the hell is Elena!”

Despite her husband saying he had no idea who the woman was, Hayek continued to take him to task, saying: “You tell that Elena that I speak English and you can practice your English with me because she sent you a message.”

After some time, the couple finally came to the realisation that the text came from a language app he had downloaded called ELSA.
