“The wedding’s off” for Britney Spears and Jason Trawick, reports In Touch, which reveals that he’s “more interested in partying… than marrying her.” The mag also notes Trawick “purchased a bachelor pad,” and she’s been “spotted without her engagement ring.” For how the singer’s handling the wedding being called off, see what a Spears friend spills to Gossip Cop.

Robert Pattinson and Kristen Stewart are planning a “secret wedding,” reveals Life & Style. The mag says the actress is so “desperate” to show Pattinson her “undying devotion” following her recent indiscretion that she’s willing to immediately “elope.” While recently in Paris, Stewart “looked at wedding dresses,” adds Life & Style. For more insider details about their upcoming wedding, go to Gossip Cop.

Jessica Simpson “caught” her fiance Eric Johnson cheating on her with his ex-wife Keri, reveals Star. The mag says Johnson even “admitted” to “sleeping with both of them at the same time.” For how the singer reacted when she found out, and why she’s convinced he’ll “likely do it again,” see what a Simpson pal confides to Gossip Cop.

Lady Gaga’s a “complete mess,” says Star, which notes she’s not only physically “getting bigger by the day,” but she’s also become “paranoid.” The magazine further reveals she “cheated on boyfriend Taylor Kinney with her bad-boy ex Luc Carl.” For why Gaga’s “sabotaging herself,” and what’s being done to prevent her “spiraling down” more, go to Gossip Cop.

Justin Bieber recently became a vegan “at the insistence of his mentor, Usher,” reveals Star. But rather than having a positive effect, Bieber’s new diet has turned him into a “jerk,” says the mag. For how becoming a vegan made the singer “vicious,” and why even his girlfriend Selena Gomez thinks it’s a “disaster,” see what a Bieber confidante tells Gossip Cop.
