Lindsay Lohan Wants McDonald's and sex

Lindsay Lohan, 20, who entered L.A.'s Wonderland rehab center on Jan. 18, has been sending Brody Jenner, 23, - former flame of Kristin Cavallari, Nicole Richie and Lauren Conrad -- sexy text messages for the last couple weeks reports Us Magazine.

In one message Lohan sent Jenner last Saturday night, Lohan said all she wanted was "McDonald's and sex."

Meanwhile, in the wake of harsh criticism that Lindsay Lohan has not been taking her recovery seriously, TMZ reports that Lindsay has decided not to star in the upcoming "A Woman of No Importance" so she can focus on getting better.

Lohan's publicist, Leslie Sloane Zelnik, says "She doesn't want to just yes everyone and compromise herself anymore," says her publicist, Leslie Sloane. "If anything has been learned, it's that what she needs comes first – and right now she needs focus."

Sloane, adds: "It's a mature thing to do. ... She's doing this so she can focus on getting better."

"Importance" is set to star Annette Bening.

"Lindsay is sad that she's unable to finally get to work with Annette, because she's a huge fan and respects her," says Sloane.

Lindsay is still slated for "The Best Time of Our Lives," shooting with Keira Knightley in London this spring.
