It may be the most tragic Valentine’s Day surprise gone wrong. Olympian track star Oscar Pistorius has been charged with murder after he allegedly shot his girlfriend in the head and arm early this morning at his home. She died on the scene. Details are still developing in the case -- some sources say the victim, model Reeva Steenkamp, arrived unannounced in the wee hours to celebrate Valentine's Day. Pistorius has had problems with burglaries before, police say, so he may have fired to protect himself and his house. Others claim he’s had issues with domestic violence in the past and this may be a very criminal boiling over of tempers. 

It was the best of times, it was the worst of times. This year saw some glorious highs, like the camaraderie and triumph of 2012 London Olympics, and some tragic, heartbreaking lows, like the Sandy Hook Elementary school massacre and Hurricane Sandy's devastation in New York and New Jersey.

We saw acts of kindness, and startling acts of rage and violence. And we reelected the nation's first African American president to his second term. Here are some of the news highlights from 2012. What else would you put on the list?

Normally when you hear about a "call girl scandal", it's because some guy -- usually a married politician -- is caught with his pants down patronizing prostitutes. It's not too often that the call girl scandal is instead a married Olympic track star who is also a $600-an-hour call girl. I mean, I don't think you ever hear that. But we do now.

Olympic track star Suzy Favor Hamilton admitted to having a double life as a married mother and Las Vegas call girl. And if the Lifetime channel hasn't opted this story yet, I'd be shocked. Anyway, let's find out what the heck is going on here ...

Well, you'd have to have been living under a rock if you didn't spend most of 2012 inundated with talk of the 2012 presidential election or Apple's much-anticipated iPhone 5. A very big rock somewhere on an island that magically had no communication with the outside world. The election, the iPhone 5, and famous-for-what-exactly Kim Kardashian grace the top of Yahoo's list of most-searched terms in 2012.

It's just the third time in the 12 years that Yahoo has been compiling the list that a news event was the year's most popular search term. In 2010, "BP Oil Spill" had that honor. In 2009, it was "Michael Jackson's death," which I guess counts as a news event. Last year we were iPhone-obsessed. What else were we searching for?

Um -- WTF? Just a few hours after he was released from jail after his arrest for fourth-degree assault, former NFL player Jerramy Stevens and Hope Solo got married -- leaving all of us wondering just what in the hell she was thinking by agreeing to marry this dude after what went down on Monday night.

The details are still pretty sketchy -- but basically a party the couple attended got very out-of-hand, and Hope wound up bloody with a laceration on her elbow, her brother Marcus Solo wound up beaten and bruised, and Jerramy -- well, cops found him "asleep" on the bedroom floor with blood on his cheek and shirt. And oh yeah, one more thing, he told police that he and Hope were arguing earlier about where they were going to live when they got hitched. (And then she turned up bloody. Hmm.)

Most people had no idea that she was engaged, but the cat's out of the bag now that Hope Solo's fiance, Jerramy Stevens, was released from jail after being arrested for fourth-degree assault.

Yes, Hope Solo has a fiance, and yes, they were planning to get married yesterday -- after dating for a mere couple of months. Ok, so who the heck is Jerramy Stevens? Turns out Hope must dig athletes, because Jerramy is a former football player for the Washington Huskies.

As to what led to his arrest, well -- apparently there was a huge party that took place in the wee hours of the morning on Monday, and things got a little out of hand (to say the least).

After Lolo Jones sent an offensive tweet to a quadriplegic man after he challenged her to a race, you'd think she'd have fallen to her knees out of pure humiliation and immediately issued a heartfelt apology -- but her response didn't even come close to making up for her blatant rudeness.

Ok, before I go on, here's what went down on Twitter yesterday. Eric LeGrand decided to have a little bit of fun with the Olympic athlete, so he sent her a tweet (as a joke) challenging her to a foot race.

And here was Lolo's eloquent reply to his request: "Get Checked for a concussion. Clearly, u’ve been hit in the head... Cos u arnt beating a track athlete." (Wow. She can run, but she definitely can't spell.)

Ever since Apolo Anton Ohno became an international speed-skating phenomenon in the 2002 Winter Olympics, I've had somewhat of a ridiculous and giddy schoolgirl crush on him. I mean, really, why not? And now that he's one of the all-stars on this season of Dancing With the Stars, he's been my immediate favorite from the start. Obviously it's too early to make predictions about the winner of the show. But I don't care. Not one bit. I'm Team Apolo all the way.

Case in point: His quick step with Karina Smirnoff on last night's episode. They pulled it off even though the rehearsals proved rather dubious. Host Tom Bergeron, after the couple got their scores (a 24.5 out of 30, psshh), told everyone watching that Apolo had accidentally head-butted Karina when rehearsing this dance. I most definitely wouldn't have minded that, but I'm sure Karina did -- yet they were still able to kick major ass. Wouldn't have expected anything less from him!
