Showing she equates sex with fast food but gives it less value, Lindsay Lohan is said to have texted Nicole Richie’s ex and Laguna Beach Reality star Brody Jenner over the weekend that she was looking for “McDonald’s and sex.”

Usmagazine.com has learned that Lohan, 20, who entered L.A.’s Wonderland rehab center on Jan. 18 to treat her addiction issues, has been sending bachelor-about-town Brody Jenner, 23, sexy text messages for the last couple weeks.

We’ve eye-balled one particularly flirtatious sext-message that Lohan sent Jenner - former flame of Kristin Cavallari, Nicole Richie and Lauren Conrad - last Saturday night in which the 12-stepper, among other requests, texted that all she wanted was “McDonald’s and sex.”

When asked by Usmagazine.com to comment on Lohan’s textual pursuit, Jenner, who just signed a deal to be a spokesman for Scope mouthwash, said, “Sorry, dude. I don’t text and tell.”

Those are probably the only two things she can’t obtain in the revolving door rehab where she’s staying. Lohan has been seen out eating and shopping, and service people such as masseurs, hairdressers, and makeup artists have been called in to meet her daily needs. Now that future male prostitute Mike Tyson has arrived to keep her company, at least one of her texted needs can be met in house.
