Lindsay Lohan and Sam Ronson: All Smiles in DC

Getting in on the Inaugural action, Lindsay Lohan and Samantha Ronson were spotted enjoying themselves at the Declare Yourself event last night (January 18) in Washington DC.

The “I Know Who Killed Me” actress and her deejay gal put to rest any remaining rumors that they aren’t together with a united front at the Jessica Alba and Jamie Foxx -hosted shindig.

According to an eyewitness, Lindsay and Sam "looked very happy together... very much the happy couple... All signs of any lovers' quarrel appear to be gone." And at one point, Lohan offered to support the shy Ronson by posing with her as the paparazzi snapped up pics.

Following the party, Lindsay and Samantha headed back to their hotel, smoking up a storm outside before heading in for the night.
