We’ve not been paying much heed to the rumours Justin Timberlake is cheating on Jessica Biel with Rihanna…. because they seemed pretty ludicrous.

But they’re not going away — and the tabs are now reporting a JT/Biel split.

According to Us, the Trousersnake dumped his buff belle during a telephone call.

That can’t be true… can it?

The 26 year old has two children with two different mothers — and another two more on the way, if online reports are to be believed.

Model Lauren London and singer Nivea — Wayne’s actual girlfriend — are both said to be pregnant with the star’s third and fourth kids.

We’d love to have been a fly on the wall when the busy boy explained that scenario to Nivea — who he is planning to marry this summer!

Paris Hilton spent her first night as as single girl partying in Hollywood with her sister Nicky.

Just hours after the socialite’s rep revealed she’d split from her boyfriend of six months, Doug Reinhardt, we ran into the Hilton sisters leaving the My House nightclub.

According to online reports, Paris wielded the axe when she spotted her beau eyeing up other girls while they were out together on Tuesday.

But we’re not convinced the whole thing isn’t just a publicity stunt.

The split came just days after Paris raved about the former baseball player in a series of TV interviews and internet postings.

And she didn’t look too broken-hearted when we spotted her just minutes later, engaging in a late-night texting session.

TMZ.com is reporting that Mel Gibson’s girlfriend, Oksana Grigorieva, is pregnant with the couple’s first child together.

The Lethal Weapon actor’s estranged wife Robyn filed for divorce last month after 28 years of marriage; the filing was quickly followed by reports that Gibson had been dating…well, which Oksana exactly was a little hard to figure out initially, but after a few days, Grigorieva was revealed as Gibson’s new main squeeze.

Gibson has apparently informed Robyn and their kids — six sons and a daughter — that Grigorieva is in her second trimester of pregnancy.  But we’re willing to bet Robyn knew a while ago, and it’s what prompted the separation to begin with.

Hot off the WENN wire is the news that reality-TV couple Katie Price and Peter Andre, photographed together on an almost daily basis of late, have decided to separate after four and a half years of marriage:

The British glamour model, also known as Jordan, and the Aussie singer confirmed the news on Monday.

A statement from the couple’s management company reads: “Peter Andre and Katie Price are separating after four and a half years of marriage.

“They have both requested that the media respect their families’ privacy at this difficult time.”

The pair, who met on the U.K. reality TV show I’m A Celebrity… Get Me Out Of Here!, tied the knot in 2005 in an extravagant wedding at Highclere Castle in Hampshire, England. They are parents to son Junior, three, and daughter Princess Tiaamii, one. Price also has a son, Harvey, from her previous relationship with soccer star Dwight Yorke.

The shock announcement of their breakup came just hours after Britain’s The Sun newspaper pictured Price cosying up to a mystery man during a drunken night out at the Syndicate club in Bristol, England — without Andre.

And news of the split ends months of speculation regarding the state of their marriage, which has been documented in their reality TV show Katie & Peter: Stateside.

More details as they come in.
