Leonardo DiCaprio and Rihanna have tried to keep their apparent secret relationship under the wraps. Now, photos secured by TMZ seem to prove the two are indeed in some type of relationship.

TMZ early Monday morning published two photos of DiCaprio and Rihanna together at her 27th birthday on Feb. 20. 

According to reports from TMZ, Rihanna seems to be very into DiCaprio. She followed him around everywhere at her party, one source alleged. 

DiCaprio helped plan Rihanna's birthday party that included the two dancing and showing off some public displays of affection. 

The couple was supposedly spotted dancing and lighting up a cigarette together.

Rumors that DiCaprio and Rihanna were seeing each other surfaced back in January when they were spotted at the Playboy Mansion for a designer Nikki Erwin's 30th birthday party.

Again, reports said DiCaprio and Rihanna were awfully close together and even kissing. One of DiCaprio's friends said no kissing took place at the Playboy Mansion, but two people who were there told TMZ they saw the two kissing.

DiCaprio and Rihanna were apparently comfortable enough to show off their feelings for each other in front of Paris Hilton, Pamela Anderson, Naomi Campbell and other stars. Afterward, the two wound up at the same after party together, along with 50 Cent.

Rihanna and DiCaprio have been secretive about their current relationship. But according to Hollywood Life, the couple is not really dating but are just hooking up and not ready to settle down to anything long term. 

"Leo is as smooth as anyone can be, Rihanna knows that he will not pursue her and it's more of a thing where they have to be at the same place at the same time," a source told Hollywood Life.
