Most couples have sparks flying around them, but for Avril Lavigne and boyfriend Brody Jenner, they throw punches - literally.

Lavigne and Jenner apparently ended up last night in a bloody bar quarrel after the latter had a bottle smashed in his face, according to E!.

The incident happened at the Hollywood Roosevelt.

As to what exactly happened, the police are still investigating the details of the brawl. Although, a reliable source tells E! that the bottle smashin' occurred when Lavigne got into an argument with another woman.

Jenner tried to stop the two ladies, but things went the other way around. Cops arrived soon after, and the Hills star was taken to a hospital with a big wound on his face.

As of press time, Jenner was already out, but not without a few stitches as a souvenir.

Before the altercation happened, he tweeted, "Having the best night with the love of my life @AvrilLavigne so happy right now!! .. #Movember CRUSH!! haha".

And what a 'crush' he got! Hours after the incident, he updated, saying "Interesting Saturday night... Just got of the hospital with a new scar on my face.. Charges/chargers!!!"

Jenner and Lavigne have been together since February 2010, after the "What The Hell" singer divorced her husband of almost four years, Sum 41 vocalist Deryck Whibley. They are said to have been tattooed with each other's name to celebrate their hook-up.

When asked if they're going to tie the knot, Jenner's mom Linda Thompson is not looking forward to that possibility just yet.

"Not yet. I mean they're young. They both have their careers to concentrate on," she says.

However, regarding their compatibility, she adds, "They have the same sense of humor. They both love to laugh and have fun. They both have a little streak of irreverence which is pretty delightful and a lot of fun to be with."

Oh, we can see that irreverence right now.

Hopefully, this incident would just be a footnote to the couple's crazy relationship and won't go as sour as her previous marriage did.

Brody's new tattoo could be seen on his left forearm - it reads "Avril". And his tattoo-loving songstress girlfriend has had "Brody" tattooed on her ribs, which was seen recently when she wore a bikini on Malibu beach. (Pacific Coast News)
