Chris Brown thinks it's ''difficult to love''.

The 'Loyal' hitmaker posted a cryptic message on his Instagram account, with speculation suggesting he was hinting at his split from Karrueche Tran or his current child support battle with Nia Guzman, the mother of his daughter Royalty.

He uploaded an image, which read: ''It is easy to hate and it is difficult to love. This is how the whole scheme of things works. All good things are difficult to achieve, and bad things are very easy to get.''

The 26-year-old singer has certainly made no secret of the fact he wants the 27-year-old model back, according to an insider.

The source said: ''Chris has been blowing Karrueche's phone up, calling and texting her. He's dying to see her in Vegas and has been pleading with her to make his birthday wish come true. All he wants to do is see her.''

And Karrueche is also reportedly proud of the efforts Chris has made to look after his little girl.

A source added: ''When Karrueche saw the photo of Chris and Royalty, she dropped her phone. She went to the bathroom for a few minutes to catch her breath and compose herself, and when she came back out and looked at it again, she smiled. The fact that Chris is finally growing up makes her happy.

''Karrueche is so proud of Chris and finds it refreshing that he's taking care of his responsibilities. She's so happy Royalty has her father in her life. It's something she wishes she wish she had when she was Royalty's age.''
