Lindsay Lohan and Ali Lohan: Sisterly Shopping

Sister act! Lindsay Lohan, 22, spent some quality time with little sis Ali Lohan, 15, in Malibu this week.

The Lohans perused the stores at the Malibu Towne Center, stopped and had pizza at D’Amores (hopefully a lot, their arms are kinda skinny), and finished up with some purchases at Pacific Coast Greens.

They bought groceries including vitamins (the legal kind, thank you), microwave goodies, and fat-free ice cream. Fat-free? Is that necessary? The two of them look like they’ve been on the starlet diet of cigarettes and Red Bull.

Do you think Ali is trying to cadge an Inaugural Ball invitation out of big sis?

Lindsay’s on-again girlfriend Samantha Ronson is spinning at the Neighborhood Inaugural Ball on a return trip to D.C.

The Neighborhood Inaugural Ball is one of the many parties celebrating Barack Obama’s ascent to the Presidency on Tuesday. And Lindsay will surely be in tow. Though some staffers at the event are worried the couple’s constant fighting could rile up the Prez.

“This is a massive gig for the pair of them and they realise it. But Lindsay will be on her best behaviour—she and Sam are both huge supporters of Obama so they wouldn’t want to ruin the evening,” a source tells the Mirror.

All the U.S. needs is two girls having one of their patented knock-down drag-outs to overshadow the historic Inauguration moments on Tuesday.

So what do you think? Will Samantha Ronson and Lindsay Lohan keep the lesbian angst to a minimum on Inauguration Day? Let us know!
