As dating rumours go, it's a bona fide head-tilter.

This weekend, reports hit the web that Charlize Theron had a new man in her life.

The Daily Mail declared on Sunday that Modern Family star Eric Stonestreet, who plays Cameron Tucker in the hit US series, was dating South African actress Theron, 37, after being introduced by mutual acquaintances in Los Angeles earlier this year.

"Charlize and Eric get along incredibly well," a so-called "source" told the website. "They started off as friends but things are blossoming between them."


Added the insider, "Eric is down to earth and funny and Charlize thinks the world of him. It's early days but they're very fond of each other."

Stonestreet, 41, who picked up an Emmy for outstanding supporting actor in a comedy on Monday, recently split from his long-term girlfriend, Broadway actress Katherine Tokarz.

Theron, on the other hand, has been flying solo since she casually dated Ryan Reynolds just before he started seeing his now-wife Blake Lively in 2011. Prior to that, she was in a relationship with actor Stuart Townsend for nine years. They split in 2010.

The actress adopted a baby boy named Jackson in March.

But here's the rub with the new romance reports - the funnyman's rep says they're hogwash.

"There is nothing romantic going on between them. He has only met Charlize twice!" Stonestreet's rep told People.

On one of those occasions they were snapped together at the White House Correspondents' Dinner in April.


Stonestreet also took to Twitter to weigh in on the rumour.

"I wish people would stop spreading rumours that Charlize Theron and I are dating. It's starting to make Halle Berry jealous," he quipped.

The actor also joked about the rumour on the Emmy Awards red carpet.

"She [Halle Berry] was so cold to me this morning when she saw these rumours," he said. "It was just quiet - fork and knife on the plate. Halle and I weren't speaking at all. And I'm like, 'Halle, listen! It's just a rumour. It's not real.'"

Stonestreet added that he "would love to know" why he's been romantically linked to Theron.

"For all of you watching at home, that's the definition of our town, that I'm rumoured to be dating Charlize Theron."

Snow White and the Huntsman star Theron dished in May that she was relishing her new role as a mother.

"I love it! I've got to tell you, I'm available for other babies' diapers to be changed. I can do it in my sleep now. I am so good," she told The Today Show. "I now know how to change a Japanese diaper, a Spanish diaper, an English diaper, a German diaper. I'm like the diaper pro now."

She added: "The one thing I'm grateful beyond anything else is that she [her mother Gerda] raised me to always encourage me to be my own person... and that teaches great independence and confidence.

"And I would hope to have my son feel the same way about himself. And kind of go and discover the world in his own skin."
