Ahhh ... and the Taylor Swift collaborative covers continue. In addition to bringing out Ellen Degeneres and Nicki Minaj at her Los Angeles show on over the weekend, Swift also had the guys from Hot Chelle Rae join her for a duet on their feel-good hit 'Tonight Tonight.'

Standing atop the enchanted, golden staircase we have seen her on throughout her Speak Now tour, Swift began singing the beginning of 'Tonight Tonight' before introducing the guys from Hot Chelle Rae. The all-guy group was greeted with shrieks from the crowd as they began to sing along with Swift. On the second verse, singer RK Follese grabbed Swift's arm -- which she has been writing song lyrics upon throughout her North American tour -- during the line "I woke up with a strange tattoo" as Swift cutely shrugged it off.

Sheesh! Do you have any more celeb friends you are hiding from us, Taylor? If this girl had a Rolodex (which we're sure she doesn't), it would be overflowing with high-profile numbers.

We're also confident that Swift slays at karaoke outings, since it seems like she has memorized about 100 songs from different artists throughout her trek across the US and Canada. At past shows, Swift has performed songs from the Beach Boys and Gwen Stefani, Eminem's 'Lose Yourself,' Bon Jovi's 'Livin' on a Prayer,' Justin Bieber's 'Baby,' plus many more.
