Love is in the air, my pop culture peeps. To catch you up on what you may have missed these past couple weeks, here are some updates on the marriages, engagements (both confirmed and rumored) and budding romances in Hollywood.

It looks like Scarlett Johansson is off the market once again. The actress, 28, is engaged to a French journalist, Romain Dauriac. Reportedly, the couple's engagement happened about a month ago. Keeping the news under wraps for that long is super stealthy by Hollywood standards, especially considering Johansson's former high-profile relationship with actor Ryan Reynolds, whom she married in Sept. 2008. Reynolds and Johansson divorced, however, in July 2011. So far, there's no word on when ScarJo and Dauriac are planning on tying the knot.

In another surprising sneak move, news broke last week that actress Zoe Saldana got married earlier this summer to Marco Perego, an Italian artist. Their relationship only became public in May, at the premiere of Saldana's film Star Trek: Into Darkness. Secret Hollywood engagements and marriages? Such madness!

TV personality Katie Couric, 56, got engaged over Labor Day weekend, adding to our tally of celebrity romance gossip for these last two weeks. Couric's banker boyfriend of two years, John Molner, apparently asked her to marry him while the couple was on the beach in the Hamptons. The beach, a gorgeous ring-it certainly looks like Molner, 50, knew what he was doing.

In addition to photographers snapping pictures of Couric and her fianc?(c)e, they also captured a playful kiss between Nick Jonas, 20, and his rumored girlfriend, Olivia Culpo, on Sept. 3. Culpo, 21, was crowned Miss Universe in 2012. The two supposedly met at the Miss USA pageant this June, which Jonas hosted along with (who else?) his brothers.

Finally, rumors that hot couple Ashton Kutcher and Mila Kunis possibly got engaged also made Hollywood headlines recently. The cause of all the engagement talk? A thin, gold band that Kunis, 30, was snapped wearing on her left ring finger. The couple worked on That '70s Show together for 8 seasons, but only began a romantic relationship as of early 2012.
So far, though, the rumors are just that-neither Kutcher's nor Kunis's reps have confirmed an engagement. Plus, Kutcher, 35, still is not legally divorced from his ex Demi Moore. Still, Moore and Kutcher were photographed last Tuesday exiting the same airplane at the Bob Hope Airport in Burbank, Calif. They had been attending a conference related to Thorn, their shared organization that fights against online predators. Is the situation complicated enough for you?

On a completely unrelated note, how about the new Dancing with the Stars casting? It's always fun to see just how loosely the show can interpret the notion of 'star.' This season's DWTS, which premiered Monday, has a cast that includes Jersey Shore's Snooki, High School Musical actor Corbin Bleu and singer Christina Milian.

I think I'll be watching this season, if only just to see everyone's favorite science guy, Bill Nye, foxtrot his way across the television screen. Hopefully, this has inspired you to take a trip down memory lane and re-watch the epic intro to Bill Nye the Science Guy, or at least gotten it stuck in your head. You're welcome.
