Pabst Brewing Co (PBC) has tried to cool a spat with Snoop Dogg after the rap star reportedly claimed a potential US$70m from its recent sale.

Dogg, who in 2011 endorsed PBC's fruit liquor range Blast by Colt 45, filed a lawsuit against the brewer yesterday claiming 10% of the sale price, according to the Hollywood Reporter. The rapper - real name Calvin Broadus Jr - reportedly said he is entitled to the money thanks to his contract to promote Blast.

In November last year, private equity firm Metropoulos & Co completed its sale of the 170 year-old PBC to Blue Ribbon Intermediate Holdings for a reported US$700m.

However, in a statement PBC said it had not been contacted by Snoop Dogg "or his representatives about this issue". The brewer said it is now under new ownership and new management but that "we are investigating the matter and would be happy to talk to Snoop... to try to get to the bottom of this".

The Hollywood Reporter said the lawsuit, filed in California, cites a clause in Dogg's endorsement that supposedly states that if the Colt 45 brand is sold within two years of the end of the agreement Dogg will receive "10% of the net price of such sale".

PBC's last owners Metropoulos & Co, Dean Metropoulos' investment fund, acquired the brewer in June 2010 from the California-based Kalmanovitz Charitable Trust.
