BIRTHDAY AVRIL LAVIGNE

It was reported earlier this month that they are heading for divorce after just 14 months of marriage.

And on Avril Lavigne's milestone 30th birthday on Saturday, Nickelback rocker Chad Kroeger was notably missing from his wife's celebrations at the Bellagio Hotel in Las Vegas.

The petite pop star partied instead with a couple of girlfriends and looked gorgeous in a pink strapless number as she was presented with a giant cupcake birthday cake.
