Rihanna reportedly reached out to ex-boyfriend Chris Brown, when she learned he had to cancel tour dates in Canada this week because he was denied entry into the country.

As part of his ongoing "Between the Sheets" tour with Trey Songz and Tyga, Brown was originally scheduled to perform at the Bell Centre in Montreal on Tuesday and the Air Canada Centre in Toronto on Wednesday.

Live Nation confirmed in a statement the two concerts have been canceled, "due to immigration issues," losing over $3 million as a result.

According to Urban Islandz, RiRi called Breezy to give him emotional support.

"No one really knows Chris like RiRi and if you know her, you will know that she is a very thoughtful and compassionate person," an insider revealed. "She gave him a call, had a little heart-to-heart with him, because he is clearly feeling a bit depressed by all the issues going on with his tour."

However, the "New Flame" singer apparently thinks current girlfriend Karrueche Tran is incomparably better than the Barbadian star in every aspect, no matter what.

"Karrueche is way different from Rihanna," a source told HollywoodLife.com. "The two don't even compare. Karrueche is like superwoman to Chris. She can do just about anything."

"She cooks like Martha Stewart," the source added. "She's funny like Mo'Nique. Her sex game is something straight out of Lil Kim's 'Hard Core' album. She's ambitious and about her money like Oprah. But most importantly, she's an elegant, classy and very intelligent woman like Michelle Obama," the source continued.

The source added Brown knows Tran is the one for him: "Chris may only be 25, but he's smart enough to know that he will never find a woman like this - ever. He's got the only one ever made."
