Looks like things between Travis Barker and Rita Ora are getting serious -- fast.

On Thursday, a rep for Barker confirmed to ET that the 39-year-old Blink-182 drummer is dating the British singer. Later that night, the two attended a black carpet event for Knott's Scary Farm, a seasonal Halloween tradition at Knott's Berry Farm in Buena Park, California.

A source tells ET that although Barker and Ora arrived and walked the carpet separately, they met up inside the venue.

Barker brought his two kids, Landon, 11, and Alabama, 9, to the event, where they posed for pics on the carpet before getting together with the 24-year-old singer.

Ora, arriving solo, wore a graphic T-shirt over a long-sleeved lace top, black leather pants and chunky combat boots.

The "Body On Me" singer stuck by Barker's side almost all night, and a source says Rita was really sweet to her new beau's kids.

They looked to be "having a great time" and were in "good spirits" throughout the night, the source confirms.

According to the source, the four of them went on the Timber Mountain Log Ride and through the Paranormal Activity maze twice. The group also went through a few other creepy mazes, including Forevermore and the Tooth Fairy maze. They all sipped on icees and, at one point, Ora started scaring the monsters back to help alleviate her own fear. 

The couple met for the first time a week ago, at the Power 106 All Stars Game at the Galen Center in Los Angeles on Sept. 20. 

"They're really into each other and have been hanging out since they met," a source tells ET.

A day after the game, Barker took to Instagram to share a photo of the two, snapped by photographer Willie Toledo.

"Me and the beautiful @ritaora at @power_106 #Power106AllStars," Barker captioned the photo.

Barker was married to model Shanna Moakler from 2004 to 2006. She is the mother of his two kids. Over the summer, Barker dated UFC ring girl and model Arianny Celeste.

Ora recently split from her boyfriend of over a year, Tommy Hilfiger's son, Ricky Hilfiger, in July. Ora was also previously linked to Calvin Harris in June and Rob Kardashian in 2012.
