Lindsay Lohan was overcome with emotion on the Late Show with David Letterman.
"Oh, she's tearing up a little bit," said Letterman.
The tears came near the end of a long interview when Letterman praised Lohan for coming on his show despite his having made frequent jokes about her troubled personal life.
Letterman said, "You have enough spine, enough sense of yourself, enough poise to come out here and talk to me," said Letterman.
But during his opening monologue, Letterman kept at it, tossing jokes at Lohan's expense such as, "If she actually shows up, I owe Paul $50."
When Lohan came out, she wore a floral dress and towering Louboutin shoes.
From the start, Letterman pulled no punches, asking, "Yes or no, do you steal stuff? Do you drink too much? Aren't you supposed to be in rehab?"
Lohan rolled with it, to a point.
"I have a list of things you've endured. Can I rundown a few things?" said Letterman.
Lohan asked, "Can I see them first?" She laughed at the list and said, "I thought you were going to be nice!"
Some thought that Letterman was too hard on Lohan.
On The View, Sherri Shepherd said, "It felt like she got blindsided."
Whoopi Goldberg said, "It was uncomfortable to watch."
Lohan posted a photo Wednesday, tweeting: "Had a wonderful time at the Late Show. It was great fun! I heart Dave."
Lohan spoke openly to Letterman about her court-ordered 90-day stint in rehab, which starts next month.
"I've been through a lot in life. I'm looking forward to actually just taking time for me," she said.
Letterman showed a photo from Lohan's first appearance on his old NBC show in 1992 a bright young talent with a brilliant career ahead of her. How different from the troubled woman we see today.
Ali Wentworth said on The View, "My kids watched The Parent Trap, with her as a little kid, all the time. I just stare at that TV and just go, 'What happened to you?' "
Lohan was all smiles as she left Letterman's show in a new outfit. And at 4:00 a.m., she was spotted leaving a nightclub still in the same outfit after yet another long night on the town.
