Drew Barrymore and Justin Long seriously in love

It looks like Drew Barrymore and Justin Long are getting serious about each other.

Long made some quick moves to show his support for his ladylove when a scheduling conflict landed both of their premieres (he is in the upcoming Serious Moonlight and she is in Everybody's Fine).

After Long walked the red carpet for his flick at Cinema 2 on the upper East Side with co-star Meg Ryan, the bubbly blond asked the actor if he was coming with her inside the theatre.

However, Justin whispered to her: "I'm being Mr. Hollywood tonight...I have another premiere to go to!"

Shortly after that, spies further downtown at the Loews Union Square, where Barrymore’s premiere was taking place, saw Long sneak in.

Later, the couple later stopped by the Tribeca Film Institute's fete for Everybody's Fine at Tavern on The Green, where they hung with Justin's good pal and Drew's co-star Sam Rockwell, while Justin's cast feted their flick without him further East at a SKYY party at Rogue Tomate. "They looked very happy. It definitely seems serious," the New York Daily News quoted one partygoer as saying.
