Lady Gaga Rules Billboard Charts, Tom Felton Reflects On 'Harry Potter' In Today's Tweet Dreams

Lady Gaga came bearing some impressive news today about her latest single, "Born This Way." The singer posted from her page, "BTW's 4th week at #1 on BILLBOARD + World Charts is both a musical+cultural triumph. Monsters it's official. You're Punk Art Pop Revolution." Gaga (pictured) also wrote that the successful song has especially great meaning to her because, "The point, with "Born This Way," is to fight for something that not everyone believes in. To overcome adversity with a message."

While Gaga fans can look forward to plenty more from the eccentric pop star, "Harry Potter" fans know their road is quickly coming to an end. With the beloved series' final installment, "Harry Potter and the Deathly Hallows: Part 2," just months away, it's not just "HP's" hardcore devotees that are getting sad about saying goodbye. Actor Tom Felton (a.k.a. Draco Malfoy) acknowledged what many of us have been thinking for some time, "Very excited and yet kinda sad about coming up to promoting the last HP. Can't wait to see the film though! Will be epic."
