Rocker Gene Simmons has been told to be on his best behaviour when he weds longtime partner Shannon Tweed in Beverly Hills on Saturday (01Oct11) - because his girlfriend of 28 years won't be amused by jokes or pranks.
The 62-year-old Kiss star finally asked the former Playboy Playmate to be his wife earlier this year (11) after a bust-up that featured on reality TV show Gene Simmons' Family Jewels - and Tweed wants this weekend's big day at the Beverly Hills Hotel to be a very special, serious occasion.
In a pre-wedding interview with U.S. news show Entertainment Tonight, Tweed clenched her right fist and told the rock star, "You make one joke at the altar, one joke... bada-bing (I'll hit you)."
And Simmons understands Saturday will be a day to keep things serious: "If you ask my opinion I'll tell you, but otherwise I won't say anything."
