Jennifer Love Hewitt is the topic of conversation for more than just her weight this week - the 28-year-old actress has some new bling on her ring finger after her Scottish actor-boyfriend Ross McCall proposed last month. The couple decided to tie the knot after nearly two years of dating, and Jennifer says the secret to their success will be how effortlessly the two get along. "It's the first time I've ever been in a relationship where you don't have to try," she told People. "And I think that's the answer. That's when you know that you're in something really good and healthy and right."

Fellow sitcomer Ali Larter will also be hitting up the altar in '08 - the Heroes star accepted (another actor-boyfriend) Hayes MacArthur's marriage proposal over the weekend, her rep confirmed this week. Ali, who has been ranting about her "mad love" for Hayes since August, tells People that she can't wait to start a family. "I look forward to that time when I'm home with babies."

Speaking of babies . . . Lily Allen has a bun in the oven! Amidst all this week's "oh no!" hype about Jamie Lynn Spears' unplanned pregnancy, Lily's baby news kind of slipped under the radar. But for Lily, who is 22 years old and happily settled down with her rocker boyfriend Ed Simons, baby news is a reason to smile this holiday season. A source close to the British singer told The Sun: "Lily could not be happier. She is thrilled to be pregnant and can't wait to become a mum. She's a real family person ... Ed's very happy. He is really looking after her."

Just as Jennifer, Ali and Lily start to plan their family futures, Katherine Heigl is putting a period on hers. The Greys Anatomy star has spent much of the holiday season planning her Utah wedding with musician Josh Kelley, which is supposed to take place just two days before Christmas. "Everyone is already so full of cheer just before Christmas. So to throw in a wedding at that time - she just loved the idea!" a friend told the press. And what better place to get married than amidst a winter wonderland?

More wedding bells to come in 2008 - so stay tuned for HollywoodUpClose's review of 2007 pregnancies and proposals!

The New York Daily News reported yesterday:

"Christina Aguilera and Jordan Bratman could be doubling their family. A reliable source says she's expecting twins."

Christina must be almost 8 months along, and she has definitely been doing lots of shopping for at least one baby lately. Should be interesting to see whether she really is expecting two little latinos!

Wedding Crashers actress Isla Fisher has finally popped - and made Sacha Baron Cohen the father of a baby girl!

The happy and engaged couple have yet to set a wedding date, but they will probably be too busy with baby duties to worry about that for a while anyway.

And we may not be seeing the comedy couple on the big screen anytime soon either. At least for her part, Isla told The Daily Mail:

"There is no way I am going to worry about missing out on work or the pressure to lose weight. At the moment I am not even planning any work. As far as I am concerned I am fully booked up in my personal life and I can't see beyond that. I plan on just coloring in books. I'll focus on that for the next few years."

But get ready to start seeing a wholllle lotta paparazzi photos of Borat Jr. in the tabloids!
