Leo May Have Ditched Rihanna For 'Fifty Shades' Star Dakota Johnson

"FourFiveSeconds" isn't just the name of Rihanna's latest hit — it's also the approximate amount of time the singer's alleged fling with perma-player Leo DiCaprio lasted.

Gossip rag Life & Style reports Leo was spotted putting his signature moves on “Fifty Shades of Grey” star Dakota Johnson at the “Saturday Night Live” 40th anniversary after party, held at the Plaza Hotel in NYC.

An anonymous partygoer allegedly told the magazine Leo “put his arm around Dakota and led her into the grand ballroom,” saying "Let's go look at all the celebrities.'”

According to the onlooker, “out of everyone he socialized with, Leo seemed to be the happiest when he was with Dakota,” adding Dakota seemed “thrilled” to be the object of Leo's lust.

With her skills, Dakota seems like the perfect girl to really whip the notorious playboy... into boyfriend material, that is.
