50 Cent was set to bring his Final Lap Tour with Tony Yayo, Busta Rhymes, and Jeremih to an outdoor venue near Phoenix on Tuesday, but the concert had to be postponed due to extreme heat. "Due to extreme heat, the show tomorrow in Phoenix, AZ is being postponed," 50 wrote on social media. "For anyone who would like a refund, please go to point of purchase for instructions. I'll be back in Arizona soon! 116 degrees is dangerous for everyone." The decision came just days after 50 did perform in Dallas despite having to endure 100-degree weather. "103 dates. This is show No. 25," 50 shared. "Live Nation set me up. Put me in Dallas. 102 fu-king degrees." The tour, celebrating the 20th anniversary of 50's landmark 2003 debut Get Rich Or Die Tryin, is expected to be his last for some time.
