Nick Carter's brother missed his wedding due to his plane being delayed.

The Backstreet Boys singer married Lauren Kitt yesterday (12.04.14), but his 26-year-old sibling Aaron was unable to attend the ceremony in Santa Barbara, California after problems with his flight from Washington, DC.

He wrote on Instagram: ''Really?? @USAirways @drakebell bro are we both sitting here?? Like really I DIDNT want to miss my bros wedding!! F**K!''

He later apologised to his brother, joking that he hopes the 'As Long As You Love Me' hitmaker doesn't ''hate'' him for missing his big day.

Aaron added: ''Really p***ed off that I missed my brothers wedding today.. i hope he doesn't hate me .. I tried to get there... I'm sorry bro @nickcarter #technicalProblems''

Meanwhile, Nick's bandmate A.J. McLean had posted his congratulations just before he attended the rehearsal dinner on Friday night (11.04.14).

He said: ''Chillin at the house getting ready to head to the rehearsal dinner of the wedding most of u thought would never happen but I'm so happy it is finally!

''Congrats to my little bro for growing up and finding love. So proud of u bro. Love u both @nickcarter and @laurenkitt (sic)''
