We didn't even realize that they were dating!

Avril Lavigne's rep has confirmed that the 27-year-old singer is engaged to Nickelback frontman Chad Kroeger, 37.

While the couple haven't publicly commented on their relationship, Lavigne did tweet back in February that the two were working on her upcoming album together (she posted the pic below and wrote "Bro'ing out with Chad Kroeger in the studio"), and today she re-tweeted a congratulatory message from his bandmates.

Kroeger reportedly presented the Canadian singer with a 14-carat diamond engagement ring on August 8. "He makes her so happy," a source tells People magazine. "Both of their families could not be more excited."

This will be Lavigne's second marriage and Kroeger's first. She filed for divorce from Sum 41 rocker Deryck Whibley in October of 2009 after three years of marriage, and in January she split reality star Brody Jenner after two years of dating.

After being questioned by police yesterday regarding a reported robbery, Lindsay Lohan's skipping town!

Linds was at Los Angeles International Airport Tuesday afternoon, headed for New York City, and while she flashed us a quick smile, she didn't care to elaborate on the incident, which is currently under investigation.

Lohan partied at a mansion in the Hollywood Hills Sunday night with her brother Cody and her assistant Gavin Doyle. The party lasted until Monday morning, which was around the time the owner of the home noticed that several expensive items from his home were missing.

A source tells X17online exclusively, "It looks like the owner of the home realized some of his personal belongings were missing [Monday] morning and he went crazy, accusing people in the house. He eventually called the cops to come investigate."

It can't be all play and no work!

Gwen Stefani has been soaking up the summer with frequent trips to the beach with her boys lately, but today the No Doubt singer headed into an LA office building to take care of business! The blonde bombshell was more dressed down than usual in ripped jeans, a black tank, and funky cinched tan heels. Something that never changes? Her signature red lips!

The 42-year-old divulged in a recent interview why she took a break from the band to pursue a solo career.

"There's nothing that compares to being in a band with your best friends you've known all these years. Playing live is so automatic and so electric. That whole period when I got to do[solo] records, to me it was indulging my theatrical side, and getting to be really creative that way; like, do costumes, and costume changes; do music that was electronic and not have to worry about a drummer or anything else - songs that were never meant to be taken seriously, just for fun. It was just a project I did that was very inspired, and it kind of got a little out of control, really. But there's no place like home; we're so comfortable together, we understand each other. It feels, like, normal. Whereas that [solo] period felt like I was trying to be something, and play a role, and pretend," she explained.

We cannot wait for the new album Push and Shove to hit stores!

TomKat no more!

A New York judge just signed off on Tom Cruise and Katie Holmes' divorce papers, officially ending their 5-year-marriage. The divorce was conducted in lightning speed, since Holmes only filed in June.

The former couple wanted a swift settlement to remain on amicable terms for the sake of their daughter, Suri, 6, who Holmes got primary custody of.

Another one bites the dust!

30 has never looked so good!

Country cutie LeAnn Rimes, rockin' a white bikini, spent her 30th birthday on the beach in Orange County with friends and family.

The "Give" singer Tweeted:

HUGE thx to @donjulio for providing the tequila and awesome mixologist for my 30th bday!!

To top it off, looks like the birthday girl got some lovin' from sexy hubby Eddie Cibrian. Happy birthday, indeed.

Justin Bieber knows how to give off that sexy vibe!

The 18-year-old "Boyfriend" singer is showing off his swagger in the pages of Vibe magazine. We're lovin' the behind-the-scenes footage from the shoot.

Biebs, whose been nominated for two MTV Video Music Award nominations, tells the mag:

"In general, fame can tear you apart, so you can never really feel like you're famous. When people start acting like they're famous, that's when they start losing it."

As for maintaining privacy, JB adds, "I don't like giving too much personal information about where I live and the cars I drive."

People can't stop talking about Miley Cyrus' new haircut, and while fans seem to have mixed feelings about her short blonde locks (in our poll, 69% of you voted that you can't wait for it to grow back), Paris Jackson has taken to Twitter to defend the 19-year-old singer.

"i don't know why people keep hating on Miley's new cut," Paris tweeted yesterday. "i love it !! shes being herself & shes being different & i love her for that !"

Fiance Liam Hemsworth also loves her look, as he recently told Good Morning America, "Her hair looks great ... It's a big change and it looks really fantastic."

Alessandra Ambrosio and her family are back from the UK, and even though they were just stepping off of a 11-hour flight, everyone seemed to be in great spirits!

The Victoria's Secret stunner pushed three-and-a-half-month-old son Noah Phoenix in a stroller, and hubby Jamie Mazur held on tight to the couple's 3-year-old daughter Anja. Just a few minutes before taking off, Ale tweeted, "all on board!!! Time to check it out my @THELOVEMAGAZINE !!bye bye europe!! Love."
