Harry Styles sparks dating rumors again, as he recently went on a concert date with a mystery brunette and was spotted with a hickey on stage.

The One Direction member attended a VIP Coldplay concert at the Ace Hotel in Los Angeles a few weeks ago with a woman, who later was identified as Daniella Monet.

The Nickelodeon sitcom "Victorious" actress is a huge fan of the "Midnight Memories" hitmakers - she previously took to her Twitter account to show her love and support while seeing them performing at the Rose Bowl. "Thoroughly enjoying the @onedirection concert right now," she wrote.

Just days after hanging out with Monet, Styles was seen with a love mark on his neck during his onstage performance. The photos of the 20-year-old Brit sporting a hickey quickly spread online, fueling speculation.

While the "Steal My Girl" crooner is yet to confirm his current relationship status, it seems like Daniella Monet is not the one who is responsible for his hickey because her Instagram page is actually full of loved up pictures with a man named Andrew, who appears to be her boyfriend.

Then, who might be responsible? Styles was romantically linked with another woman in Austin, Texas a couple of weeks ago. A video of him riding a mechanical bull at a bar with a mystery blonde sitting in front of him has surfaced on the Internet. Also, an eyewitness @meagan_stokes claimed seeing him and his bandmate Niall Horan in a series of tweets:

Although fans immediately speculated that Harry Styles got a new girlfriend, Sugarscape insisted that the unidentified woman is "just a friend of a friend, acting as a tour guide for Harry around a city he wanted to explore."
