Cool Entertainment Happenings in Las Vegas This Weekend

With the Las Vegas temperature cooling a tad this weekend (if 100 degrees is better than 110 for you), it’s a great time to get out and about, blissfully frolicking in all the tempting merriment.  Here’s our Las Vegas Backstage Access Best Bets on a roll:  Usher is walking the red carpet at 7 p.m. tonight at the Playboy Club at the Palms.  Jenny McCarthy will be at Pure nightclub at Caesars Palace on Saturday, walking the red carpet around 11:30 p.m.  Judas Priest and Whitesnake will be whaling away at Thomas & Mack on Saturday night. No Doubt and Panic at the Disco will perform tonight at the Hard Rock.  Country singer Alan Jackson will be at M Resort’s outdoor piazza on Saturday. If extreme cagefighting is your cup of tea, check out the diminutive Miguel Angel Torres and Brian Bowles as they fight for the coveted WEC bantamweight championship at 3 p.m. on Sunday at the Hard Rock Hotel.   If soothing your nerves is the order of the day, take in the cool relaxing jazz from Elvis Costello’s hot wife, Diana Krall, as she performs at The Pearl at the Palms at 8 p.m. on Saturday.  For a great blast from the past, listen to Gladys Knight as she pips away today through Sunday at 8 p.m. in the Showroom in The Orleans.  Whew!
