LOS ANGELES (Reuters) - Lindsay Lohan, fresh from her latest stint in jail, will appear on The Tonight Show with Jay Leno on Tuesday, NBC said. 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.
