Leonardo DiCaprio and his father went to lunch in West Hollywood yesterday, and we've seen the two out and about before, but it never ceases to amaze us how different they look!

It was recently reported that Leo introduced girlfriend Erin Heatherton to his mom, so maybe she'll get to meet his dad next? We're sure George DiCaprio would approve of the 22-year-old Victoria's Secret model ... who wouldn't?

On Tuesday evening Zac Efron attended the Lakers game at the Staples Center in Los Angeles, and the hunky actor was in a great mood when we spotted him in the parking lot afterwards. Kobe and company beat the Phoenix Suns 99-83, so there were lots of happy basketball fans in LA last night!

P.S. Is it just us, or does Zac look super tan? Think it's from a vacation or a tanning bed?

Robert Kardashian's ex-wife Jan Ashley claims in a new interview with Star Magazine that Khloe is NOT the late attorney's daughter!

"Khloe is not his kid -- he told me that after we got married," Jan told the mag. "He just kind of looked at me and said [it] like it was a matter of fact. He said, 'Well, you know that Khloe's not really a Kardashian, don't you?' And I said, 'OK,' and that was it."

And she's not the only one! Apparently Ellen Kardashian, who married Robert after he separated from Jan, has also come forward to talk about the Kardashian family's secret in the new issue of the gossip glossy.

While Khloe has not yet issued a denial about the report, she did respond to the news on Twitter this morning, and it sounds like she's furious! "The audacity you have to mention my father’s name like this! Should be ashamed of urself! I let a lot of things slide but this one is really low," she wrote. "YOU ARE DISGUSTING! (yes you know who YOU are)." But will she sue? We'll keep you posted!

Halle Berry and Olivier Martinez have decided to tie the knot, according to various online reports.

X17online brought you the first photos of the Oscar-winning actress' emerald and diamond engagement ring. Martinez, 46, proposed to Ms. Berry, 45, over the holidays.

The couple, who met while filming the movie Dark Tide, went public with their relationship in 2010.

This will be the third marriage for Halle. She married baseball player David Justice in 1993, and they divorced in 1997. The Monster's Ball actress then married R&B singer Eric Benet in 2001 and divorced in 2005. Most recently, she and model Gabriel Aubry dated for close to five years. They are the parents of 3-year-old daughter Nahla.

Reps for Halle and Olivier have not yet released a statement.

Madonna has named her 12th studio album M.D.N.A..

We have a feeling we'll learn what the abbreviation means soon enough! But it's a bit ironic that MDMA is also the name for the drug ecstasy. Always pushing the envelope!

Madge will hit the stage on February 5th in Indianapolis for Super Bowl XLVI where she'll be performing her latest single "Give Me All Your Love."

Most recently, the "Like A Virgin" singer was in Switzerland with her family and young boytoy, Brahim Zaibat.

There's no stopping this pop icon ... even at the age of 53! Having a young boyfriend probably helps.

Ashton Kutcher has lost his wife but gained a sweet, new ride!

The Two and a Half Men actor, not wearing a wedding ring, cruised around LA in his Fisker Karma sports sedan. The eco-friendly ride costs an estimated $88,000!

For years, Ashton and his soon-to-be-ex Demi Moore have been very vocal about being green ... owning several Lexus hybrid sedans and a Prius.

This new silver sports car definitely isn't your mama's hybrid. In fact, the Fisker Karma has an “Eco-Chic” interior, which uses no animal products and features wood reclaimed from forest-fire salvage logs, renewable resources like bamboo, and even logs that sank into rivers years ago.

Good looking and good for the environment. Yes, we're talking about the car.

Bradley Cooper and girlfriend Zoe Saldana have been living together for months, and here are the pix to prove it!

We've seen the twosome at Cooper's LA home many times ... morning, noon and night.

An X17 photographer tells us:

"These two really don't want to go public with their relationship for some reason. They never ride in the same car, they're never seen together in public. They're such a great-looking pair, I don't know why they hide."

Until now, Brad and Zoe have been very discreet ... making sure to not leave or enter the house together.

So much for keeping their living arrangements on the down low.

Jillian Michaels could become a mom in 2012!

The Biggest Loser trainer made the choice to leave the show last year so she could focus on starting a family, and now Michales can finally confirm that she will soon welcome a baby girl!

Jillian revealed to Access Hollywood Live:

“I’ve been matched with a little girl, but, I now have to get her home… It could take up to a year to get her home.”

The fitness guru confessed that going through the process of trying to adopt a child from Haiti isn't easy, but after meeting the little girl while on a trip there, she knows it will be worth the wait.

“I’m actually so excited. The government shut down almost, [and] all I could think about was my 600A [immigration adoption] form ... So now I’m this much closer and all the paperwork is done. It just needs to go to the various embassies — it’s a godsend,” she said.

Congrats!
