Engagements

'Big Bang Theory' actress Kaley Cuoco has found her knight in shining armor in tennis player Ryan Sweeting after only three-months of dating (following a possible PR romance with Henry Cavill). The duo are engaged to be married.

Those of you familiar with 'The Bachelor' probably remember that macadamia with "sparkle" and a whole lot of catfights, Tierra LiCausi, from Season 17. She fell in love with Sean Lowe pretty much immediately, then when she got booted from the 'Bachelor' mansion, she fell in love with someone else ... and promptly announced her engagement on the 'Women Tell All' reunion special. Well, tha

So much for any hope of a Miley Cyrus-Liam Hemsworth reunion. The couple, who confirmed that they'd called off their engagement earlier this week, are totally dunzo ... and Hemsworth has already moved on with another lady. And, to the surprise of many, it's not January Jones.

Congratulations to Carlos Pena, Jr. and Alexa Vega! The Big Time Rush singer and the 'Spy Kids' starlet are engaged!

Actress Scarlett Johansson and her boyfriend, journalist Romain Dauriac, are engaged, according to recent reports. In that case, let's pop open the hypothetical champagne.

Singer and actress Christina Milian is engaged to longtime boyfriend (and CEO of Rap-A-Lot Records) Jas Prince, and we wish them all the best.

Congrats are in order for adorable TV and talk show host Katie Couric. The anchor got engaged to John Molner, her boyfriend of two years, over the Labor Day holiday weekend.

Lance Bass, who made a whole lot of us squee when he and the rest of 'N Sync reunited at the VMAs last weekend, recently did something else that was cause for celebration: He popped the question to his boyfriend of almost two years, model Michael Turchin.

John Mayer and Katy Perry are back together in a big way. It's not only good for their careers (they keep gushing about one another to the press to promote their new albums 'Paradise Valley' and 'Prism'), but also for their hearts. Turns out, Mayer is even considering taking the next step with Perry. What's that step?

Ashley Tisdale got a huge sparkler from fiance Christopher French, and she had a good time flaunting it.

Just weeks after rumors of a Robert Pattinson-Kristen Stewart reunion surfaced, onetime K-Stew co-star Riley Keough has completely put rumors of her own R-Pattz romance to rest for good -- in a big way.

Actress, singer and former Disney star Ashley Tisdale is reportedly engaged to boyfriend Christopher French, and apparently it all went down at the top of the Empire State Building. Just like in 'An Affair to Remember.' Except not.

Kelly Clarkson is the cutest, happiest bride to be we've ever freakin' seen, and in her engagement photos she showed that in addition to being adorable, she's also stunning.

In a bizarre move that's actually not close enough to his album dropping to be considered just a publicity stunt, DJ Khaled proposed to Nicki Minaj on video. Except Minaj wasn't even there.

In addition to breaking the hearts of delusional Maroon 5 and 'The Voice' fans everywhere, Adam Levine broke another heart when he announced his out-of-the-blue engagement to model Behati Prinsloo. Yet another swimsuit model, Nina Agdal, was devastated by the news.

Congrats to Rose McGowan. The 'Jawbreaker' actress is now sporting a backbreaker on her all-important finger after getting engaged to artist Davey Detail.

Adam Levine may joke that he's not a romantic (because that's what happens when you say you take women to McDonalds on dates), but his fiancee, Victoria's Secret model Behati Prinsloo, knows differently.

Congrats to Adam Levine! The Maroon 5 singer, who goes through supermodels like water, is now engaged to on-again off-again -- currently very much on-again -- love Behati Prinsloo.

Kelly Osbourne is engaged to her boyfriend of two years, Matthew Mosshart. And if it seems like you've heard this story before, well ... you have.

Halle Berry swore up and down that she'd never get married again, but it looks like the third time may be the charm. The Oscar winner has been engaged to fiance, future baby daddy, French actor and former boxer Olivier Martinez since March 2012, and it looks like they may walk down the aisle this weekend.
