'Watch your back' - Ryan Reynolds threatens Paddington Bear on Twitter

It appears Ryan Reynolds doesn't discriminate when it comes to choosing a target for his next Twitter take-down - even including beloved fictional bears.

The Deadpool star set Paddington Bear firmly in his sights this time - telling him to "watch his f**king back' with reference to the People's Choice Awards.

"So honoured by all the @peopleschoice noms," Reynolds tweeted.

"Hope you vote for Deadpool 2 and feel free to write us in for best Family Film.

"Because watch your f**king back, Paddington".

He may be cute and cuddly, but Paddington came in hot and fixed Reynolds with one of his trademark 'hard stares' in retaliation.

"#hardstare," he replied, which is especially impressive considering his lack of opposable thumbs.

Of course, it wasn't long until the Internet lost its collective mind over this latest social media smack down, with many of Reynolds' own fans stepping in to defend the bear from Peru.

"This tweet was going so well until the last sentence. Don't be disrespecting the Bear, Reynolds," wrote one online commentator.

"I'll be honest Ryan, your movies are some of my favourites, but you ever talk about the legend that is Paddington Bear again and we're going to rumble!" said another.

Even British actor Hugh Bonneville, who plays Paddington's foster dad in Paddington 2 had a few choice words for the Hollywood A-lister.

"Language, Mr Reynolds, language," Bonneville said.

So while it seems Paddington can well and truly hold his own, I'd strongly suggest that Winnie The Pooh sleeps with one eye open.
