The absence fueled rumors that Lavigne and Kroeger are drifting apart and possibly heading towards a divorce.

Avril celebrated at The Bank Nightclub in the Bellagio Resort and Casino in Las Vegas.

The “Hello Kitty” singer wore a pink dress and was accompanied by her closest friends.

Earlier this week, sources close to the rockers told Us Weekly that Lavigne and Kroeger were about to separate after constant fights.

“It’s over,” a source told the magazine. “He has been going around L.A. telling people that they are divorcing.”

The couple tied the knot in July 2013 after a one-year engagement.
