Louis Tomlinson is apparently "disappointed" Zayn Malik missed his mom's wedding.
The 22-year-old One Direction star's mother Johannah Poulston married Daniel Deakin in a sunny outdoor ceremony at the end of last month.
Louis was joined by his bandmates Harry Styles, Liam Payne, Niall Horan and stylist Lou Teasdale.
However fifth member Zayn, 21, opted to spend time with his fiancée Perrie Edwards and her family instead.
"Louis was very disappointed that Zayn decided not to attend his mom's wedding," a source revealed to British magazine Star.
"The boys have been through so much together over the past four years that their families have all grown close, so Louis was upset at the no-show.
"They know Zayn wants to spend as much time as possible with Perrie, but they were both welcome to come together to the celebrations."
There have been rumours for a while that Harry, 20, may leave the band in favour of a solo career. Footage of him singing alone has emerged and he has also written material for other musicians. However, he recently clarified he has no intention of abandoning the boys.
Instead, insiders fear it could be Zayn who decides to break away from the pack.
"Zayn is feeling really disconnected from the rest of the band and wishes he could spend more time with Perrie," the source continued.
"It wouldn't surprise the lads if he is the first to jump ship."
