First, Nick Lachey
told PEOPLE there was very little truth
to reports he might get back together with his newly single
ex-wife, Jessica Simpson
Now comes bad news for fans hoping Simpson’s ex-boyfriend John Mayer
will heal her broken heart.
"Absolutely not," Mayer's pal Rob Dyrdek, 35, star of MTV's Fantasy Factory
, told PEOPLE Monday at Ryan Scheckler's X Games Celebrity Skins Classic" in Coto De Caza, Calif.
Mayer and Simpson dated on-and-off for about a year before splitting in 2007. Dyrdek says he "wouldn't rule out" a reunion, but adds, "I'm just saying [I don't think so]."
Earlier this month, Mayer found himself in the middle of Simpson's breakup with her boyfriend of a year and a half, Tony Romo, when reports surfaced that he had been texting the pop star, 29. In May, a source told PEOPLE the exes "have been in touch."
Mayer observers may remember Dyrdek, a pro skateboarder, as the apparently drunk friend the singer carried out
of L.A. club MyHouse June 14. Mayer Tweeted later that night that he was with Dyrdek at the hospital as he had his stomach pumped.
It was a prank.
"He's one of the most incredible people I have ever met and a thoroughbred genius," Dyrdek says of Mayer. "He just likes to [mess] with the paparazzi. He's like, 'I want to do so much more crazy [stuff],' and he settled on carrying me out of the club."
The faux-scandal will be part of Fantasy Factory
. "I did a whole episode on what it's like to have a psychotically famous [friend]," Dyrdek says. "Just the whole idea of how out of control it got. To where my parents' local news was like, 'Local celebrity almost dies.' "
The practical jokers later devised a creative way to tell Dyrdek's mother they were sorry. "We recorded a song called 'Rob's Mom' that apologizes to her and all of the girls in the office."
