Word is Jacoby Ellsbury and his wife, Kelsey Hawkins, are planning a party to celebrate their wedding, and several of the Sox centerfielder’s teammates will be attending. We’re told the couple, who quietly tied the knot last month, is throwing the party in Arizona, where they live during the offseason, at the end of the month. The 29-year-old Ellsbury (inset), the 2011 AL MVP runner-up, may not be in Boston much longer. He can become a free agent after next season and is occasionally mentioned in trade rumors. . . . Meanwhile, the budding romance between Sudbury-bred “Captain America” star Chris Evans and actress Minka Kelly is still going strong. Paparazzi snapped the cute couple holding hands the other night as they walked out of Bootsy Bellows nightclub in West Hollywood. Kelly got together with Evans after ending her relationship with Yankees shortstop Derek Jeter.
