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.

Some stars, like Charlie Sheen and “Glee” stars Jane Lynch and Lea Michele opted for “no photos” but were happy to lend their signature for a good cause.

Grammy Award-nominated group Mumford and Sons shared a laugh while photogs snapped away before they rocked the house poolside at The Boulevard Pool at The Cosmopolitan in Las Vegas on Friday (April 15).

Opening for the quirky quartet was alternative new comer Kristian Matsson, who goes by his stage name “Tallest Man on Earth”. The show was sold out solid, we hear, but not before on-screen music lover Jeremy Piven nabbed a ticket!

Up next for the group was their biggest performance to date — at the Coachella music festival!

“This is going to be the biggest show we will have ever played, which I only found out a couple days ago,” frontman Marcus Mumford explained to Rolling Stone. “It’s kind of strange, playing a gig like this after only one album. We’re very lucky and blessed.”
