Hostile Hollywood!

Star caught these celebs in all-out arguments!

JESSICA BIEL & JUSTIN TIMBERLAKE

Just last year, Justin made no secret of the fact that he’d like to have a big family. “I want to have as many kids as we can, if I’m being honest,” he told an interviewer, gushing about how much he loves being dad to his 4-year-old son, Silas. But it looks like his dream has gone bust.

A source tells Star that Jessica, 37, isn’t keen on having another kid — and that she and Justin, 38, are constantly at odds over expanding their family. “They had a huge fight about it,” the insider dishes. “She’s furious that Justin wants her to put her career on hold. They’re not in a good place, and bringing another child into the situation is the last thing Jessica wants.”

PORTIA DE ROSSI & ELLEN DEGENERES

It’s all fun and games with Ellen on her daytime talk show, but the state of her relationship with wife Portia is no laughing matter. In fact, the couple’s decade-long marriage is hanging by a thread, with Ellen’s relentless work schedule to blame. “Portia wants Ellen to quit her daytime talk show, since it stresses them both out,” says the insider, adding that Portia, 46, is demanding Ellen, 61, take a break from the spotlight — even though the TV personality insists she can balance her career with her relationship. However, a huge argument erupted between the two in January after Ellen publicly defended Kevin Hart in the wake of his antigay tweeting scandal. “Lately the tension is off the charts,” adds a source, “and friends are starting to think the relationship won’t last.”
