Is there "Bad Blood" between Taylor Swift and Harry Styles?

After racking up eight wins at Billboard Music Awards in Las Vegas Sunday, Taylor and her musical BFF Ed Sheeran threw a star-studded party for the event's fellow attendees. Taylor's boyfriend Calvin Harris showed up, of course, as did Adrian Grenier, David Guetta, Fifth Harmony, Jennifer Lopez and Pentatonix, among others. One Direction's Niall Horan and Louis Tomlinson also posed for a picture with Swift that night. Given Taylor's romantic history with Harry, his absence didn't go unnoticed. "Harry didn't stay in Vegas after the awards, so [he] didn't attend any after-show party," the boy band's rep told E! News Tuesday. Interestingly, it was Taylor's brother, Austin Swift, who shared the snapshot on social media.

Harry dated Taylor briefly from 2012 to 2013, and it's believed that he inspired several of the song's on her latest album, 1989, including "Clean" and "Out of the Woods." (Swift's policy is to never publicly identify who inspired her lyrics.)

So, what's Harry doing in L.A.?

A source tells E! News he had dinner at Ysabel with Ed and Courteney Cox Monday.

Of course, there was another notable absence at Taylor and Ed's party: Rita Ora. The British pop star broke up with Calvin in 2014, and, as a source told E! News Monday, "Rita Ora totally broke his heart...He never expected to feel betrayed."

Regardless of where she stands with Calvin, Rita is a big fan of his famous girlfriend. "I think she's one of the most incredible songwriters of our generation. I'm not even just saying it. I absolutely adore her music and love what she stands for," the "I Will Never Let You Down" singer told Vice in a Q&A published Monday. "You pay respect to people who deserve it—Beyoncé and Madonna. When Madonna was going through it on this last record, I was one of the first people to post my support on Instagram. Don't battle her because of her age. I'm a girl's girl, I support women, and it comes back to you. I'd love that support. There's a fine line between believing in yourself and being a f--king a--hole. I don't step on people's toes."
