Pop star Christina Aguilera took to the stage at last night’s ‘Justin Timberlake & Friends’ concert in Las Vegas. Preceding her performance of ‘Beautiful’, the soon-to-be-divorced diva was introduced by Timberake as “with no competition, the best singer of our generation”.

Her performance after the jump…

Though Timberlake’s comments are open to interpretation, it’s hard to deny Christina’s vocal prowess. That said, this performance didn’t particularly move me. Yes, it was was technically quite sound; however Aguilera has performed it markedly better on many an occasion. Still, it can’t be that bad when you’re primary point of vocal comparison is yourself, can it?

Your thoughts?
