One Direction star Louis Tomlinson danced with a dwarf during a raucous bachelor party in Spain ahead of his mother's wedding.

The singer attended his soon-to-be stepfather Dan Deakin's wild bash in Barcelona on Friday (16May13), and the night was one to remember.

According to Britain's The Sun on Sunday, the group hired 'Little Sarah', a dwarf performer who donned a policewoman's uniform and brandished a truncheon while entertaining Deakin and his pals in their suite at the W Hotel.

Taking to Twitter.com on Saturday (17May14), Deakin wrote, "What a night! From what I can remember."

Deakin is set to wed Tomlinson's mum Johannah this summer (14).
