Tyga hopes that Blac Chyna and Rob Kardashian will be happy together.
The 26-year-old rapper has a three-year-old son King Cairo with Blac, but is now dating Rob's sister Kylie Jenner.
Rob's relationship with Blac has caused controversy among his family, but Tyga isn't worried about the romance.
When asked about the relationship while out with friends, Tyga told E! News: "Everybody deserves to be happy."
Not everyone is as accepting of Rob's new partner, however.
It was reported this week that his sister Khloé, with whom he has lived for the past few years, kicked him out of her house when she came home to find him swigging bottles of booze with Blac.
A source told TMZ.com: "Khloe became enraged and asked Chyna, 'What the f*** are you doing in my house?' The two bolted into Rob's wing and locked the door. Khloé followed suit and told them both to get out. Khloé made it clear to Rob, he was no longer welcome in her home."
The reality TV star believed she had no choice but to chuck out Rob, who has become reclusive over the past 24 months, to teach him a lesson out of fear he was falling off the wagon again and Blac was preying on his weakness.
The insider said: "Rob's sister was especially indignant when she learned Rob had purchased some expensive items for Blac as he doesn't have a lot of money to burn."
Rob is now believed to be living with Blac.
