Amanda Seyfried and Justin Long made their relationship official when they made their first joint event appearance at the LAByrinth Theater Company's annual celebrity charades benefit in NYC last night. Amanda and Justin joined Saturday Night Live stars Bobby Moynihan and Rachel Dratch, as well as Rose Byrne and her Emmy-winning boyfriend, Bobby Cannavale, on the stage for a round of lively games. While Amanda looked happy to play with her beau at the bash, she gave some insight into one of her relationship no-nos when she tweeted sage love advice earlier this month, writing, "Stop tweeting your significant other." Maybe Amanda's tweet reveals why Justin rarely tweets at his blond lady, except when it's to praise her performance in Lovelace.
