Here's the scoop on the juiciest relationship news in Hollywood this week:

Hookups:
-Leonardo Dicaprio has had one busy 2011. He's jumped from blonde to blonde to blonde over the last 12 months! His latest catch? Hot Victoria's Secret model Erin Heatherton. Sources say the two have been dating since the beginning of December, and this week she flew from NYC to Australia to hang out with her new man. While Down Under, she reportedly dropped about $1,700 on fancy lingerie. Ooh la la! An insider says they'll fly back to the Big Apple together tomorrow and will ring in 2012 together.

- Here's some juicy news: Sources say Maria Shriver might be having second thoughts about divorcing Arnold Schwarzenegger! The trusty sources over at TMZ say Shriver is unsure of what she wants to do partly because of her strong religious beliefs that go against divorce. And, Arnie is reportedly buttering her up with gifts and acts of kindness. Shriver bought a Brentwood mansion shortly after moving out of the family home months before filing for divorce in July, after news of the Governator's love child surfaced. Stay tuned.

Breakups:
- Another big name in sports is headed for splitsville. Just days after Kobe Bryant's divorce was made public, Deion Sanders and his wife Pilar announced their breakup after 12 years of marriage. This couple, however, has a prenup. That doesn't mean Pilar won't come out of the split empty-handed, though. TMZ reports under the provisions in the agreement, she gets a house equal to half the value of whatever their current home is. Their 30,000 square foot, 10 bedroom home has a listing price of $21 million. Sources say the soon-to-be ex-Mrs. Sanders is shopping for homes in the $9-12 million range. Not too bad at all...

- Debra Messing is back on the market after 11 years of marriage, sorta.The Will and Grace actress announced she and writer-producer Daniel Zelman had split, but also says they will continue to live together for the sake of their 7-year-old son. "The decision was mutual," Messing's rep said in a statement. "They remain supportive of one another and committed to raising their son as a family. They have been separated the better part of the year but continue to live together in New York for Roman." Sources say the breakup was "very amicable." The family recently moved from L.A. to NYC, where Messing is filming her new series, Smash.

Babies:
-It's a boy for Dido! We know, you probably haven't thought about the singer-songwriter in a while, but she's been busy with married life and welcomed a baby in July. The tot, Stanley, was presumably named after the song that made her popular in the US. "Stan" was the name of Eminem's 2000 single, which sampled her hit "Thank You." The singer wrote on her Facebook page about spending the holidays with her little guy. “I’m ridiculously excited about stanley’s first christmas this year!” she wrote. This is the first child for Dido and husband Rohan Gavin.

- Kid No. 6 came just in time for the holidays for Robert De Niro. The 68-year-old actor and wife Grace Hightower welcomed baby Helen Grace via surrogate. The couple also has a 13-year-old son, Elliot, while the actor has four other children ranging from 16 to 40. De Niro and Hightower met in London in 1987 and renewed their vows in 2004. Clearly they're still going strong and have a lot more parenting ahead of them!
