Music fans were well-served this weekend as an array of musicians was added to the usual lineup of actors, actresses and reality-show personalities playing in Las Vegas.
From shock rock and punk-pop to rap and R&B, there was a show in town for almost every music-loving concertgoer.
While he doesn't "Party All The Time" anymore, Eddie Murphy partied ahead of time, before the weekend even started. The DJ at Jet played Murphy's 1980's collaboration with Rick James after the actor and fellow partier Arsenio Hall were spotted in one of the club's corner booths on Thursday.
VH1 reality TV star Joanna Hernandez was also at Jet that night. The For the Love of Ray J contestant was at the club with a group of girlfriends, according to witnesses.
Murphy and Hall later moved the party over to Tao, where Flava Flav joined them.
Rihanna stopped by the popular Venetian nightclub much later that night -- so late, in fact, that it was technically Friday morning. The stylish R&B songbird showed up around 4 a.m. with a few friends.
Meanwhile, boxer Fernando Vargas made his Thursday night appearance next door, at Lavo. He and a group of male friends were spotted drinking Grey Goose in the club's VIP.
Also at Lavo on Thursday: actress Missi Pyle and her husband, National Geographic Expedition Grizzly personality Casey Anderson. The couple was in town celebrating Anderson’s 34th birthday and had dinner in the main level restaurant.
Ludacris kicked things off on Friday and gave a free concert at the Palms Pool.
The rapper was spotted at N9NE Steakhouse before the concert where he and six others enjoyed dinner in a large booth. Ludacris reportedly ordered sea bass, creamed corn and lobster mashed potatoes as his pre-performance meal.
Before he left, Luda reportedly took the time to pose for a pictures with a few fans, including N9NE head chef Barry Dakake. He later unwound after the show at Playboy Club where he and a friend played a few sexy hands of blackjack.
Also at N9NE on Friday was actor/producer Seth Green, who was in town with his girlfriend who was celebrating her birthday. The couple was also spotted at a VIP table at Moon nightclub later that night.
Big Bad Voodoo Daddy was also in town this weekend and performed poolside at the Hard Rock Hotel on Friday.
Shock rocker Marilyn Manson was also at the Hard Rock that night. He and opening act September Mourning shocked and rocked The Joint.
Among the gothy concertgoers was decidedly ungoth Adam Goldstein, who is better known as Rain's Friday night resident turntable master, DJ AM. Pro dirtbike rider-turned-tattoo-shop-operator, Carey Hart, was also at the concert.
Manson was spotted at the hotel's steakhouse, Rare 120, the night before the show, as was Slayer guitarist Kerry King .
Green Day and Franz Ferdinand also performed on Friday night. Their show was on the Strip, over at Mandalay Bay.
Later that night, Will.i.am of the Black Eyed Peas added to the night’s musical offerings and took to the turntables at Rain following a shortened set by DJ AM.
The award winning and creative force appeared onstage just after 2 a.m. and played for about an hour. While Will.i.am’s performance wasn’t announced until 5 p.m. on Friday, the real surprise came midway through his set, when two of his three fellow Peas, Taboo Nawasha and apl.de.ap, joined him onstage. Together, the three performed a handful of the Peas' hits but no, Fergie did not join them.
Professional poker player Michael Matusow was also at Rain on Friday, and headed to Moon from there.
Lauren Conrad was also in Las Vegas this weekend and kicked things off with dinner at Tao on Friday. In town for her cousin's bachelorette party, she and a group of ladies, including her mother, continued their girls night at the second-floor nightclub after their meal.
The party continued on Saturday with dinner and more dancing at Lavo.
Before that, however, Conrad hosted the first of two star-studded pool parties that took place despite the abnormally gray and rainy on Saturday afternoon.
The Hills star had lunch at SushiSamba before heading to Tao Beach, while acclaimed American Beauty actress Mena Suvari, lounged by the pool next door at the Palazzo.
Suvari’s appearance was part of Azure’s ongoing vodka-infused promotion, Absolut Saturdays.
Later that night, Knocked Up, Superbad and Pineapple Express co-writer Evan Goldberg was spotted inside the Palazzo as he had dinner at Lavo.
Meanwhile, Jermaine Dupri was next door, at Tao, where he partied until about 3 a.m. with a friend and a bodyguard.
Actor and DJ Danny Masterson (aka DJ Mom Jeans) was also at the club that night and drank Patron with his friends while they partied on the club's catwalk.
Rounding out the Tao round-up is basketball players Jermaine O’Neal (Miami Heat) and Tracy McGrady (Houston Rockets), who were also spotted at Tao on Saturday.
Boyz II Men were further south on the Strip on Saturday as the group gave a throw-back show at Mandalay Bay Beach.
Meanwhile, rock band Daughtry made a stop at Caesars Palace and played an all-ages show at Pure.
Rounding out the Saturday night musical ticket was legendary English rockers Depeche Mode. The group performed at The Pearl then hit the stage-side VIP at Rain after the show.
Actress Sarah Lancaster was also at the Palms on Saturday as she and a group of friends celebrated her brother's 21st birthday. She and the nine other birthday partiers were spotted at Playboy Club that night.
And finally, Aid for AIDS of Nevada’s (AFAN) 23rd annual Black and White Party supported a good cause and featured a handful of local headliners, too.
Ms. Coochie Coochie herself, Charo; the sexy casts of Men of X and X Burlesque; longtime Evening at La Cage impressionist Frank Marino; comic magician Nathan Burton; and entertainers Penn & Teller were among the notable guests that turned out for the very-worthy cause.
