Chris Brown, Rihanna, Karrueche Tran Love Triangle: Chris Attends Monster Tour After Sending Rihanna Instagram Love [PHOTO]

Singer Chris Brown was spotted backstage at Rihanna and Eminem's "Monster Tour" in Pasadena, California at the Rose Bowl stadium trying to win back the "Diamonds" starlet back after dumping Karrueche Tran.

According to Urban Islandz sources, Chris tried contacting the 26-year-old celebrity and was shut down, "He has been texting her nonstop and blowing up her phone begging to meet with her but surprising this time she is holding her ground and told him no," the source added, "She basically told him straight up she don't want him or his basic chick anywhere near her. Robyn [Rihanna] is in a better place now, she is more content and focus on herself and her career."

Unfortunately, pictures obtained by Bossip.com, Rihanna is shown passing by a smiling Chris Brown in a crowded area backstage. Although the pair may never be a couple again, sources say she is still in love with the 25-year-old bad boy, "RiRi will always have love for Chris Brown but she accept that they can't be together she is way to mature for him."

August 6^th, the singer posted a cryptic message about his trust issues which he later deleted before making his ex, Karrueche his "WCW" before deleting the post.

It seems Chris and Karrueche are really over and the "Loyal" singer is still stuck between two women.

What should Chris do?
