In perhaps his strongest comment since early November regarding his free-agent future, Carmelo Anthony appeared Tuesday night to second his wife La La’s remarks from the previous day. In promoting her new book, “Love Playbook,’’ La La Anthony said in a Bravo interview she “definitely thinks’’ Anthony will re-sign with the Knicks following this season. When The Post asked Anthony, who has an opt-out clause in his contract, about the remark following the Knicks’ win over the Celtics, he said: “That’s my wife. I support her. I don’t think she said anything wrong. It’s a good thing for her to say that. “Go get the book though,” Anthony added. “Definitely your wives and girlfriends will enjoy the book.’’ With the book’s release Tuesday, La La broke some news in the tome, finally denying Kevin Garnett told her husband she tasted like Honey Nut Cheerios during a Celtics-Knicks game last season. Anthony’s celebrity wife had never denied the incident that occurred in a Garden game last January. “I wasn’t ever going to bring up the Honey Nut Cheerios incident again. But since I’m writing this book, I might as well set the record straight for good,’’ La La wrote. “Kevin Garnett in fact had never said that I tasted like Honey Nut Cheerios. I tried to figure out how this big lie was turned into a media firestorm. I still can’t answer that one. … Melo and Kevin are cool today. And now it’s nothing but a faint memory.’’ That said, Garnett’s trashtalking was damaging. La La revealed Anthony had choice words for Garnett on the court and then afterward when Anthony confronted him near the locker-room area and by the Celtics team bus. Anthony received a one-game suspension for the offcourt confrontations.
