Lindsay Lohan, fresh from her latest stint in jail.

 Lindsay Lohan, fresh from her latest stint in jail, will appear on "The Tonight Show with Jay Leno" on Tuesday and in a last-minute addition to the lineup, the "Mean Girls" actress taped her appearance on Monday, but officials at the network declined to reveal what the two discussed.

Lohan was sentenced to four months behind bars on Friday for violating her probation, and jailed for about five hours before her legal team scrambled to post $75,000 bail. Her latest legal woes stem from the alleged theft of a $2,500 gold necklace while she was on probation for a 2007 drunk driving and cocaine possession incident.
Lohan was ordered to stand trial on June 3 but the jewelry charge was reduced to a misdemeanor from a more serious felony, and will cut to one year her maximum time behind bars if eventually convicted. In the meantime, Los Angeles judge Stephanie Sautner ruled that Lohan had violated her probation, and sentenced her to 120 days in jail and 480 hours' community service. Lohan's lawyer filed an immediate appeal as the actress was led away.
