Embarking on the second U.S. leg of her "The Truth About Love" Tour, P!nk kicked off her two-night stint at the STAPLES Center last night with a bang.

Opening act The Kin's strong performance was a hint of all the good things to come. The Australian/New York-based band treated fans to songs off their new EP "Get On It" (released just last week), including the title song and "On the Rise," while also playing old favorites like "Never Be the Same."

Co-lead singers and twin brothers, Isaac and Thorald Koren's vocal performances were on point and drummer Shakerleg impressed fans by playing the drums without any sticks - which explains the number of bandages and tape on his hands!

The Koren brothers also brought along a little bit of Australian culture by bringing out the didjeridoo, a traditional Aboriginal instrument, during their set.

In between sets, a mysterious man appeared in the crowd to mess around with fans, even going so far as to licked a bald man's head!

Eventually, the man's identity was revealed as Ruben - the host for the night - and he was on the look out for someone in the audience to come onstage and "learn the truth about love," at which point the camera turned to a pre-recorded shot of P!nk in the crowd.

After Ruben left the stage and the venue went dark, P!nk blasted up in the air with harnesses in an electric acrobatic performance of "Raise Your Glass," flipping and twisting her way through the song.

The concert continued on with more energetic performances like "Walk of Shame" and "U + Ur Hand" until P!nk began slowing things down with "Try," during which the singer and a male dancer re-created the passionate dance from the song's music video.

P!nk also covered two classic '80s songs over the course of the night - Chris Isaak's "Wicked Game" and Cyndi Lauper's "Time After Time."

STAPLES was filled with laughter as P!nk cracked a lot of jokes and Ruben appeared at various times throughout the set to do crazy things like fly over the crowd in a Cupid outfit and lead the audience in a gospel-like chorus of "Hell yeah!"

In an article I wrote last month, I named P!nk one of 9 musicians to follow on Twitter because of how approachable she is online. The same can be said of the singer at concerts.

P!nk constantly thanked her fans, crew, dancers, and band during her set and graciously accepted the many gifts thrown onstage, including stuffed animals and a teddy bear backpack for her daughter Willow (although the singer apparently misses the days when she'd get blocks of cheese instead).

The singer also took the time to sign autographs for a few very lucky fans throughout the night.

The crowd danced and sang along to high-energy performances of "Just Give Me a Reason" (featuring a pre-recorded video of fun.'s Nate Ruess singing), "Are We All We Are" and "Sober," which was completed by the singer wearing a variation of her iconic 2009 MTV VMAs purple outfit.

P!nk then slowed things down with a piano performance of "The Great Escape" off her latest album "The Truth About Love" (2012). She did amazingly well for someone "attempting" to play the instrument!

Next up, the singer and guitarist Justin Derrico played an acoustic version of her 2008 hit "Who Knew," much to the crowd's excitement.

While P!nk ran offstage with fan gifts to do a quick wardrobe change after "F*ckin' Perfect," backup singers Jenny Douglas and Stacy Campbell kept the audience pumped up while Derrico pulled off an amazing guitar solo.

The next segment began with a video montage of P!nk throughout the years before the singer reappeared to do a three-song mashup from her debut record "Can't Take Me Home" (1997).

P!nk then performed "Slut Like You" and "Blow Me (One Last Kiss)" as if she were ending the night then, but then she came back for an amazing aerial and acrobatic version of "So What" and this performance certainly explained why the STAPLES was completely filled up with fans, even in the "nosebleed" section!

The singer soared, flipped, and spun her way through the STAPLES Center, getting close to fans in all sections of the venue. P!nk then left the stage again, before coming back for one more encore performance.

Surprisingly, she chose to end the night with "Glitter In the Air" - a slow song off her 2008 record "Funhouse." Nevertheless, fans were screaming and singing along enthusiastically when P!nk appeared in her 2010 Grammys performance outfit to spin on silks and dip herself in water.

The concert then officially ended with a list of credits and a video showcasing funny antics behind the scenes as well as some adorable shots of P!nk's daughter Willow.

With this exciting performance, P!nk has definitely given fans a reason to keep following her on her journey to tell everyone "The Truth About Love."
