Ed Westwick reassured a stranger's wife the saucy texts her husband had received were actually meant for him.
The heartthrob - who is currently on a promotional tour with Virgin Mobile - had given out his number for fans to send him messages.
However, some female admirers misdialed and sent steamy texts to another man's phone - whose furious wife then discovered them.
Ed said: "I gave the number out and I have been bombarded with text messages.
"The funny thing is I got a call from this guy saying his number was very similar to mine and could I send a message out as he was getting all these texts from girls."
He added to Absolute Now: "It wasn't too good for his marriage but hopefully I've helped him out now."
Ed - who plays billionaire Chuck Bass in the show - had his own heartbreak in April after he discovered his girlfriend and co-star Jessica Szohr had allegedly cheated on him.
