Met Gala 2015
Rihanna's Met Gala 2015 dress designed by Guo Pei featured a long train and was the viral hit of the weekReuters

It was an eventful week for proud father Chris Brown who shared a sweet moment with his daughter Royalty on Instagram before exposing the woman who bizarrely broke into his Los Angeles home and got into his bed while completely naked.

Over on Twitter, pop divas Katy Perry, Madonna and Lady Gaga buried their tangled feud once and for all by cosying up together for a photo which they hoped would #breaktheinternet.

As everyone weighed in on Beyonce and Kim Kardashian's red carpet fash-off, Diamonds songstress Rihanna was busy dazzling photographers with her exquisite Chinese gown.

RiRi has such a sense of humour that she joined in on the memes that went viral, Photoshopping pizzas and omelettes into the extravagant train.

In case you missed it all, IBTimes UK has rounded up the best social media posts from showbiz this week...

Happy 40th birthday, David Beckham

Becks celebrated the big 4-0 in Marrakech with his nearest and dearest, including wife Victoria Beckham and their four children.

The ex footballer joined Instagram to mark his special day and within hours, he was a total pro at the photo-sharing site, writing witty captions and starting a trending topic with a snap of the Spice Girls reunion.

Kim Kardashian and J.Lo bum shots

They have two of the most famous bums in showbiz so it was only right that the reality star and American Idol judge showed off their common assets in one photo.

Even better is that Kardashian's husband Kanye West had the pleasure of taking the photo in question.

Chris Brown's very naked birthday surprise

It was a 26th birthday the Loyal singer will most likely never forget.

After dodging a criminal investigation into a reported brawl at his Las Vegas hotel, Brown then returned to his Los Angeles home to find a stranger laying in his bed wearing her own birthday suit.

Not quite the birthday surprise he was expecting!

Not only had the woman made "several meals" in the R&B singer's mansion, but she even threw out clothes belonging to his 10-month-old daughter Royalty. Fortunately, the child was safe and Brown shared this adorable photo of his sleeping beauty:

Ed Sheeran and James Blunt flirting

Now there is a sentence nobody ever thought they would read! The British crooners got all excited after realising they will be in Australia at the same time later this year.

What started off as friendly banter got a little weird:

Rihanna memes her Met Gala dress

The FourFiveSeconds singer went viral thanks to her lavish Met Gala gown designed by Guo Pei. Never afraid to laugh at herself, RiRi joined in on the meme action and shared some of her favourites including this gem:

Nina Dobrev packing nightmare

It seems no one hates moving house more than the soon-to-be former Vampire Diaries actress who shared her packing woes with her five million Instagram followers.

This facial expression pretty much sums it all up:

Katy Perry with Madonna and Lady Gaga - bury the feud

Madonna has feuded with Gaga who has feuded with Perry, but it is all water under the bridge now. Three of pop's biggest divas buried the hatchet at the Met Gala and wanted the world to know that there are no hard feelings by posing for a photo together.

Now that the ladies are all BFFs, maybe they can record a collaboration together?

What a special and amazing night to be with the people I love
