Evelyn Lozada -- Stuck With Ochocinco

OCHOCINCO, PARTY OF ONE ... is what Evelyn Lozada will be saying for the next few weeks, since she's currently the only Ochocinco left in her family. Let us explain ...

When the "Basketball Wives" star got married in early July, she changed her last name to Ochocino to match her NFL star husband, Chad Ochocinco. A few weeks later, Chad went ahead with his pre-planned move to switch his name back to Johnson and Evelyn planned to change her name to Johnson as well, post-wedding.

Unfortunately, we're told Lozada has not received her official marriage paperwork yet ... and she can't legally change her name to match his until it comes in.

To make things even more complicated ... our sources say Chad still wants Ocho to be part of his life, so he's adding the Ochocinco BACK to his name (before the "Johnson") after the football season.

After all the name-changing is said and done, he's going to be "Chad Javon Ochocinco Johnson" and in a show of support, Evelyn will become "Evelyn Alexandra Lozada Ochocinco Johnson." Wow.
