Jenny McCarthy and Carmen Electra reunited for a love(less) fest in L.A.!

The still-scorching-hot actresses co-hosted the SVEDKA Vodka Anti-Valentine’s Day Bash at AGENCY Boutique Nightclub in Los Angeles, and took out some healthy anger on their ex’es…

The twosome wrote messages to their exes (including Jim Carey and Dennis Rodman) and pinned them on the XOXO Wall for all to see. Jenny quoted a wise Rihanna when she wrote “We Found Love In A Hopeless Place…” while Carmen quipped, “Oops! You really missed out!!”

LOLz! …Ouch!

Also spotted at the bash was “Bachelor” alum Jake Pavelka, who normally hands out red roses, but was photographed bestowing black ones from Petals LA on his new brunette mystery beau, Ashley. Bad news? Also at the bash was “Entourage” actor Jeremy Piven, Adrianne Curry (the very first “America’s Next Top Model”) and ”Dancing with the Stars” pro dancer Cheryl Burke.
