In this week's A-List Insider:

Chris Brown talks about Rihanna's romance, Mia Khalifa attacks Lady Gaga and Kylie Jenner has some explaining to do.

Chris Brown talks about Rihanna's romance

Chris Brown really is the gift that just keeps on giving. Just days after he and on again off again girlfriend Karrueche Tran stormed New York fashion week in over the top matching furs, he has given ex-girlfriend Rihanna his blessing to jump back in the dating pool.

The r'n'b star said if reports that RiRi is dating actor Leonardo Dicaprio are true then he is happy for her.

"In that situation, I just tip my hat. I'm not a hater. I'm not envious. I don't feel jealous... I'm like, do your thing. I can't have it all, brotha. I can't have it all," he said during a radio interview with Hot 97.

Although Rihanna has yet to confirm whether Leo is her new man, it's still awfully-mature of Chris. I guess there is still hope for him yet.

Mia Khalifa attacks Lady Gaga

Meanwhile, it looks like Mia Khalifa is coming for all these celebs this year. The Pornhub Queen, has just crossed Lady Gaga off her burn book.

The Lebanese-born adult film star launched a scathing attack after Mummy monster turned up at the 2015 Oscars in a voluminous white gown by Paris-based designer Azzedine Alaia and red gloves.

Like many fashion critics, Mia was not a fan of the singer's unflattering ensemble and couldn't help but lampoon her.

"When the #Oscars are at 8 but your mama said to have the dishes done by 8:30," captioned a snap of Gaga's red carpet look. Ouch!

First Drake, and now Gaga. Wonder who Mia's next victim will be?

Kylie Jenner shows of killer curves

And finally Kylie Jenner's bootylicous bottom has got everyone talking.

The 17-year-old reality star sent tongues wagging after she shared this selfie showing off her derriere which seemed to have appeared overnight.

Remind you of anyone? (inset Kim swimsuit selfie) According to some eagle-eyed fans, the reality star, who allegedly had a lip augmentation last year, has gone under the knife again to achieve those killer curves.

"Kylie Jenner grew a butt and lips in less than a year and my hair can't even grow an inch" one follower claimed.

To me it looks like a combination of good angles and squats. What do you guys think?
