Adele, LMFAO and Rihanna have been nominated for a load of Billboard Awards

Mononymous popstars Adele and Rihanna are among the fron­trun­ners for this year's Billboard Music Awards.

Adele leads the field with a total of 18 nom­in­a­tions, just one more than apo­lo­getic party rockers LMFAO. Rihanna was short­l­is­ted in 13 cat­egor­ies, ahead of Lil Wayne and Lady Gaga, who have 10 nom­in­a­tions 'apiece'.

With awards going for Top Social Artist, Top Streaming Song (Audio), Top Streaming Song (Video), different awards for Top Digital and Radio songs plus three Christian music cat­egor­ies, the Billboard Awards are surely some of the most coveted in the business.

The not-at-all-drawn-out ceremony will be broadcast from Vegas' MGM Grand on Sunday May 20. Tune in to see if Adele picks up Top Artist, Top Billboard 200 Artist, Top Hot 100 Artist, Top Female Artist, Top ETC ETC ETC.
