Britney Spears may not be sure whether she wants K-fed back in her life or not, but one thing’s for certain – her ex has moved on to greener pastures. Kevin Federline has been spotted out and about with LA Radio personality and part-time model Liz Hernandez, aka “Luscious Liz.”

Seems the couple first met about 18 months ago when she interviewed the aspiring rapper for her radio show on Power 106. At the time, she asked him which of his famous ex-loves, Shar Jackson or Britney Spears, was better in bed.

According to sources, Kevin is over the moon about his new galpal and “talks about her all the time.” Apparently, he is quite “serious about her.”

Liz, on the other hand, would prefer to keep the relationship on the down-low because “she doesn’t want it to get around work.”

Imagine the talk around the water cooler at Power 106 today.
