Natalie Portman, Reese Witherspoon, More Round Out December Love Report

This month was full of celebrity engagements, weddings and a few breakups.

December has been an interesting month for Hollywood in the love department. There have been several shocking splits and even more engagements, with one seemingly pouring in every hour on the hour.

Let's also not forget that some couples tied the knot. As December wraps up, MTV News is taking a look back on a busy month for love.

The Engagements

Tony Romo and TV sports reporter Candice Crawford (sister of Chace Crawford) kicked off engagement-palooza earlier this month when they announced they were going to marry. Quickly all of Hollywood joined suit with LeAnn Rimes, Lily Allen and Ginnifer Goodwin all getting engaged.

Two of Hollywood's most famous actresses also announced their engagements this month. Reese Witherspoon announced Tuesday that she will marry Hollywood agent Jim Toth, and Natalie Portman had a lot of good news, sharing that she is set to marry "Black Swan" ballet dancer Benjamin Millepied and that the two are expecting a baby.

The Weddings

Nicole Richie and Joel Madden married in mid-December after having four years and two kids together. We assume they just wanted to make sure they really liked each other before they said "I do."

On Tuesday we learned that Chris Hemsworth and Elsa Pataky tied the knot. And finally, "Lord of the Rings" actor Billy Boyd also married this month.

The Breakups

It was surprising to hear that Scarlett Johansson and Ryan Reynolds were divorcing after two years of marriage, but the couple confirmed the news in mid-December. Equally shocking was the news that Zac Efron and Vanessa Hudgens were separating after several years as one of young Hollywood's favorite couples.

Filming for the upcoming season of "Dexter" might be a little awkward now that the show's star, Michael C. Hall, and his TV sister, Jennifer Carpenter, are divorcing. And just this week, fans learned that Rihanna and her baseball beau, Matt Kemp, decided to split because of their busy schedules.
