Aerosmith singer Steven Tyler was quite the popular ringleader last weekend when he hit the stage of Las Vegas' MGM Grand to rock the iHeartRadio festival, a star-studded two-day bash marking the launch of the new iHeartRadio application. He was joined during his sets by a string of all-star collaborators, including Jeff Beck, Sting and sultry ‘X Factor’ judge Nicole Scherzinger.

Tyler performed four songs with Jeff Beck, including covers of the Kinks' 'You Really Got Me' and Sly and the Family Stone's 'Thank You (Falettinme Be Mice Elf Agin).' That second tune also featured original Family Stone member Cynthia Robinson, who raised the roof with her surprise appearance (on a potentially sad side note, reports suggest reclusive Family Stone legend and namesake Sly Stallone is homeless and living in a van in Los Angeles).

After the success of their performance, could another Beck/Tyler collaboration be in the pair's future? "The rest is yet to reveal," Tyler told "If I had my way, I’d say yes. We did 'Cry Me a River' and an Etta James song. [We] went to rehearsal to learn these four songs. Two we knew and we just wound up filling in the breaks with all kinds of crazy stuff."

For his part, Beck was stoked to share the stage with the Aerosmith singer. "Big gigs are not my thing for the sound purposes, but when you’ve got [Tyler] there he carries the weight, 100 percent," Beck said. "I enjoyed the fact that everybody was digging what he was doing, so my job was a lot easier."

Sting joined Tyler for a rousing rendition of Aerosmith's "Sweet Emotion" that kicked off the second night, and Scherzinger followed for a take on his solo hit, ‘Feels So Good.' Despite reports that Tyler was annoyed with his original placement on the bill (he wouldn't say exactly where he was supposed to be), leading off the show turned out to be the perfect slot. "When you know you’re gonna slam ass you go on first," Beck raved. "I love the way you’re thinking."

Meanwhile, backstage in Vegas, Tyler backed up Aerosmith bassist Todd Hamilton's recent claim that the band is eying a spring 2012 release for its next album. "Two months [recording] and we’re almost there," Tyler said. "We’re gonna spend another month [recording] in Los Angeles ... [it'll be out by] March, hopefully."
