Are former One Direction group mates Harry Styles and Zayn Malik still feuding? Styles recently celebrated his 23rd birthday in a party in California. The singer was also showered with well wishes on social media, including messages from his former bandmates Liam Payne, Niall Horan and Louis Tomlinson. Relatively quiet on the Twitter sphere was Malik, fueling speculations of an ongoing feud between the two.

Styles threw a "low-key" birthday bash in Café Habana in Malibu, California, The Daily Mail reported. The party was attended by Styles' closest friends in the industry, including Adele, Cuba Gooding Jr. and Cindy Crawford. "They were doing tequila shots and taking turns on the karaoke all night long," a source says.

The source adds, "Harry seemed to be having a great time with a small group of friends."

There was no sighting of Styles' One Direction boys, but they greeted him happy birthday on Twitter. Payne, Horan and Tomlinson were one of the first to greet the "Dunkirk" actor on Twitter. Malik, however, didn't post anything related to Styles or his birthday.

Some speculate that Malik and Styles are still not on good terms after the former exited One Direction. Shortly after Gigi Hadid's boyfriend left the group, he allegedly dissed the One Direction guys for icing him out when he just wanted to be friends. Styles reportedly retaliated by saying Malik was only talking about One Direction to get attention and boost his record sales.

Meanwhile, Styles is the next former One Direction member to release his own solo album. The 23-year-old inked a deal with Columbia Records and is slated to release his solo album titled "Authentic."

"We're close and we're very excited," Columbia Records CEO Rob Stringer told Billboard. "We have a record we're incredibly excited about and it's not far away from being ready. We obviously want everything to be beautifully done, because we think he's here to stay. Harry has stepped up with the vision of someone who's authentic."

There's still no word yet as to Harry Styles' solo album release, but fans can see him next in Christopher Nolan's World War II film "Dunkirk," out in theaters on July 21.
