Haha/Oh dear. Ali Lohan, sister of Lindsay, was on Letterman last night, presumably to promote her and mama Dina's ominous new reality show. And, poor thing, as Dave was signing off, he accidentally called her Lindsay. I mean, how could he possibly get them mixed up? Lindsay is a once-popular tween idol with substantial drug and alcohol problems. Ali is a soon to be once-popular tween idol with substantial drug and alcohol problems. Geez. It's like comparing apples and the seeds that later become apples. Clip above.

As thrilled as we were to see Dina Lohan’s pity party come to life in a preview from Living Lohan yesterday, we truly wish those suits over at E! had picked the other guiding light in Lindsay’s life to trail around with cameras. A tipster alerted us to this clip, showing just another night out on the town (well, in a trailer) for Michael Lohan. We’re not sure which is more jarring: Michael’s impressions of both Cousin It and Dina Lohan, or the reminder that countless famewhores exist out there so desperate for fame they will venture into a trailer with Michael Lohan just hoping he’ll hire them to be Lindsay’s new BFF.

We rarely take a moment to thank E!'s Department of Reality-Based Famewhoring Enterprises for the excellent work they do, giving the egregiously underpublicized—everyone from the Kardashian girls to Denise Richards—a weekly hour to, well, just be. So, thanks! But with Living Lohan (why does that title remind us of a disease-awareness billboard campaign? "I've been Living Lohan for 7 years now, but Lohan isn't living me,") they've truly outdone themselves, giving Dina Lohan the vehicle we know she's wanted and deserved all along. In this preview clip, the celebrity momabler is captured in medias crisis-control, berating an online tabloid concern for publishing blurry photos of her most successful accomplishment in a compromising, probably accurate situation; watching this fierce tigress protect her largely unemployable, fur-coat-swiping cubs is truly a sight to behold.

· Get ready for the summer of exploitation on E! If Denise Richards or Dating Nightmares doesn't do it for ya, might we interest you in the White Oprah and her fame-starved daughter Ali? Nothing warms our cockles like the sight of a table full of sycophantic slags toasting a 14-year-old's non-existant career with champagne! [E!]

As much as we poke fun at Momager/Pimp Dina Lohan for her questionable parenting techniques and famewhore-y tactics to become just as cool and famous as her bankable daughter Lindsay, we secretly can't ignore the fact that having her as a mother might simply be loads of fun. Sure, you don't really have a role model, and you can't expect anyone to pick you up after school, but it's not like you go to school anyway! In Ali Lohan's case, you go to Las Vegas. MSNBC.com reports that Dina and Ali hit the strip to shoot scenes from their upcoming reality show Living Lohan and, from the sounds of it, had a grand ol' Britney Spears-in-garters kind of stay...
