BETHLEHEM, Pa. — The Twitter feud two months ago between Eagles running back LeSean McCoy and the Giants is causing some current awkwardness in the Philadelphia locker room.

Ex-Big Blue wide receiver Steve Smith, who bolted for Philadelphia last week, received — and continues to receive — a frosty reception from McCoy for joining Osi Umenyiora and Justin Tuck in the nasty social-media firefight between NFC East rivals.

McCoy started the conflagration in June when he wrote on Twitter that Umenyiora is soft, overrated and no better than the Giants’ third-best defensive lineman.

Umenyiora responded by referring to McCoy as “she” and comparing him to garish pop singer Lady Gaga.

Tuck also blasted McCoy publicly, and Smith joined the fray by tweeting a picture of the Eagles’ empty trophy case superimposed over the Giants’ 2008 Super Bowl celebration. Smith also blasted McCoy on Twitter for having “the nerve of certain youngins running their mouth.”

Smith sought out McCoy in the locker room last week after signing with the Eagles in hopes of putting the matter to rest, but McCoy was having none of it.

“I talked to him the first day and told him it was all a joke and just Twitter stuff,” Smith said yesterday. “[But] it’s going to take a little time. He wasn’t the happiest. He said he meant what he said, so hey, it’s all good.”

Approached after the Eagles’ morning practice, McCoy scowled at the mere mention of Smith’s name and made it clear hard feelings remain.

Asked by The Post if he told Smith he was still upset when Smith tried to clear the air, McCoy said: “Yeah, something like that.”

When questioned if he could get over it and be close with Smith, McCoy pursed his lips.

“I’m just here to play football,” he said.
