Though there seemed to be a lull in big Tinseltown news these past couple weeks, it looks like the gossip mill has finally started churning again.

First things first, folks-Mila Kunis is pregnant! Last Sunday, E! Online broke the news that the actress and her fianc?(c) Ashton Kutcher, 36, are expecting a child together. Kunis, 30, reportedly attended a prenatal yoga class in Hollywood just prior to E! Online's confirmation of her pregnancy. You may recall that this pop culture column had traced all of the false-alarm engagement rumors that had plagued the Kutcher/Kunis romance until last month's revelation that they became engaged for real.

The two were first linked back in April 2012, and they have never been all that shy about their public displays of affection. Kutcher was still legally married to Demi Moore (their divorce was not finalized until this past November) when he started dating Kunis. He and Kunis go way back, however-they starred as characters Kelso and Jackie in the popular sitcom That '70s Show in the early 2000s-though they did not begin dating until years after the series ended. From on-screen couple to engaged and expecting, I can almost hear the collective swooning of all those That '70s Show fans.

In other celebrity baby news, celebrity gossip outlet Just Jared reported that Christina Aguilera finally confirmed her pregnancy on Friday while attending an event in Kuala Lumpur, Malaysia. At the same time, the singer, 33, revealed that she is expecting a girl with her fianc?(c), film producer Matt Rutler, 28. Though news outlets began reporting on Aguilera's pregnancy last month, this is the first time she has confirmed the news herself. Aguilera already has a six-year-old son, Max, with her ex-husband Jordan Bratman.

Last Tuesday, Gwyneth Paltrow and Coldplay front man Chris Martin announced their separation after more than 10 years of marriage. Paltrow, 41, officially broke the news on her lifestyle website, under the title "Conscious Uncoupling." Paltrow and Martin, 37, married back in 2003 in a secret wedding. Together, they are parents to daughter Apple, 9, and son Moses, 7. The couple's split was made all the more surprising after they were spotted vacationing together on the island of Eleuthera in the Bahamas.

Our last piece of Hollywood gossip gets a bit bizarre. Months after Zac Efron broke his jaw (supposedly from slipping on a puddle and falling), the actor suffered yet another injury. On Thursday, People Magazine confirmed that, around midnight on Sunday, March 23, Efron became embroiled in a fight with two vagabonds in the Skid Row area of downtown Los Angeles and was punched in the jaw in the process.

But what was Efron doing there? The Los Angeles Police Department confirms that the actor and another male (who numerous media outlets claim was Efron's bodyguard) allege that their vehicle ran out of gas and they were waiting for a tow truck. Supposedly, a bottle was thrown out of Efron's vehicle and landed near the two transients, which spurred the fight. No one was arrested. Efron, who completed rehab treatment almost a year ago for drug and alcohol abuse, was seen in good spirits the following evening at a comedy show with friends.

There you have it-this week's roller coaster of pop culture news.
