Los Angeles - Janet Jackson got emotional as she performed a tribute to her late brother Michael Jackson on the opening night of her 'Unbreakable World Tour' in Vancouver, Canada, on Tuesday evening.
The 49-year-old pop legend returned to the stage for the first time in four years at the Rogers Arena and wowed the capacity crowd with a 32-song set packed with her greatest hits.
But when she sang the track 'Scream' - which she recorded as a duet with her brother Michael in 1995 - Janet broke down, showing she is still in pain over his death in June 2009 at the age of 50.
Janet opened her show with an as-yet unnamed track - rumoured to be called Burn It Up - from her new album 'Unbreakable' which featured Missy Elliott rapping.
Before the music hit, a video of swarming birds, seemingly inspired by Alfred Hitchcock's The Birds, played on a giant screen as Janet delivered a spoken word monologue praising her fans.
Then a recording of Elliot appeared on two giant screens which framed Janet's silhouette and the R&B icon took centre stage to provide vocals over the high energy pop tune.
Before the concert kicked off, Elliot took to Twitter to wish her friend and long-time collaborator luck with her live return, tweeting: "Positive vibes to my sis @JanetJackson the opening of her tour 2night! U r UNBREAKABLE Do ya thang (sic)"
Other stand out moments during the concert included 'Control', 'What Have You Done for Me Lately', 'All for You', 'All Nite (Don't Stop)' 'Black Cat', 'No Sleeep' and 'Rhythm Nation'.
Janet closed her show with 'Unbreakable', the title track from her upcoming new album which is due to be released later this year.
Following her live return, Janet thanked the fans in attendance for making it an unforgettable night.
She posted on Twitter: "Hey you guys, Thank you for making No Sleeep #1 again & for showing so much love at last night's show in Vancouver. Love Janet #NoSL333P (sic)"
