Pop star Robin Thicke was forced to pull out of a concert in Ontario, Canada on Tuesday night (11Mar14) after experiencing a recurring vocal problem.
The singer had to postpone the first three shows of his Blurred Lines Tour last month (Feb14) after battling undisclosed "vocal issues", before making his live comeback onstage in Fairfax, Virginia on 27 February (14).
However, the ailment appeared to return this week, prompting him to scrap a planned performance at Casino Rama near Toronto on Tuesday, a day after he celebrated his 37th birthday by partying in Hollywood with pals including Leonardo DiCaprio. The gig has been rescheduled for 26 July (14).
Thicke has since resumed his trek by playing for fans in Detroit, Michigan on Wednesday night (12Mar14).
Hours before showtime, he took to his Twitter.com page to write, "I'm really excited to be playing at @FoxTheatreDET tonight. Who's coming to see me?"
The vocal issue isn't the only problem Thicke has been dealing with - he separated from his actress wife Paula Patton late last month (Feb14) after almost nine years of marriage.
