Lindsay Lohan has secured a six-figure deal to promote a clothing company.

The Liz & Dick star - who was sentenced to 90 days in rehab this week after pleading "no contest" to charges for lying to police about driving during a car crash last June - is set to fly to Brazil this coming week, where she is scheduled to make several public appearances to promote a fashion brand, that has yet to be identified.

The 26-year-old star will earn a lot of money during the trip, with sources telling gossip website TMZ.com that she has inked a low six-figure pay packet as part of the deal.

The troubled starlet, who has been battling to pay off hefty tax debts and was allegedly forced to beg a friend in New York City for the loan of a place to stay because she couldn't afford rent recently, will fly to Rio de Janeiro with a small entourage.

Lohan, who has been in rehab five times since 2007, was recently hit with another huge tax bill of US$56,717.90 from 2011, and still has two other outstanding payments to make.

The promotional trip will take place after she films scenes for her friend Charlie Sheen's show Anger Management.

Lohan must enter a rehab clinic, where she will reportedly be treated for alcohol dependency and an addiction to prescription drugs, before May 2.

However, insiders previously admitted they are unsure how well the course of treatment will go, as the actress still doesn't think she has a problem and only agreed to go to rehab to avoid jail.

Upon completing 90 days there, she is due to perform 30 days of community service and will under go another 16 months of therapy.
