One of the companies, Vivid Entertainment, wants both the girl-on-girl and guy-on-girl configurations — but another company has already gotten a hold of one of the tapes and is angling for the second.

A source close to the negotiations tells us it’s an all-out porn war to sign Tila and distribute the tapes.

Of course neither company can do anything without Tila’s permission.  We’re guessing that won’t be a problem.

But Tila just told TMZ, “If anyone out there is trying to leak a private and personal sex tape of me that was not meant for the public, I will swiftly deal with my lawyers!”

TMZ spoke with Erica Langston … who confirms she did make a sex tape earlier this year while she was in Miami for the show … but she’s not sure it will ever hit the shelves.

Sources involved with the situation tell us the tape features Erica with her boyfriend (pictured above) and another woman … a woman who happened to co-star with Erica on “BGC.”

Erica tells us she’s considering releasing the tape — but not until she can work out a legitimate deal.

BTW — we asked Erica about the identity of the “other” woman … but this time, her lips were sealed.

A TMZ photog saw the whole thing go down just minutes ago — as Danielle was served for a defamation lawsuit her ex-boyfriend Steve Zalewski is bringing against her.

Danielle was just starting down the red carpet at a Halloween event in Woodridge, NJ when the process server walked up with an envelope and said, “Here, Danielle … you’ve been served.”

Danielle was stunned, but didn’t miss a beat — she simply handed the envelope to her publicist and continued down the red carpet into the party.

According to sources, Zalewski is suing Danielle for defamation
because she has repeatedly accused him of secretly shooting a
sex tape of her — which he denies doing.

Well-placed sources connected with “Two and a Half Men” tell us … the sober coach is living at Charlie’s house and accompanying him to work. 

Charlie has spent time with sober coaches in the past, with mixed success.
