WTF! -- Beyonce & Solange Knowles Sleep Through Japanese Earthquake

A huge earthquake may have shaken Japan – but Beyonce Knowles' sister Solange slept right through it!

The quake – the second in two days – measured 6.5 on the Richter scale injuring 43 people and causing a nuclear power plant to shut-down.

But singer Solange Knowles who is in Japan with her famous sister Beyonce amazingly was left unstirred by the huge shaker which swayed buildings causing ornaments and shelves to collapse.

Solange tweeted: Praying for everyone affected by this – Wtf ! Wtf ! Wtf ! my sister said she was scared out of her mind and calling my mom and I was snoring. 6.6 ??? Omg! Omg ! omg ! tsunami watch ??? how did I sleep through a SERIOUS earthquake. AGAIN. Japan. Wtf ?

It struck shortly after 5am (local time) with an epicenter located in the Pacific Ocean around 105 miles south-west of Tokyo.

Television footage showed supermarket floors littered with foods while the bullet trains between Osaka and Tokyo were suspended.

Singer Jessica Simpson – who is also currently in Japan – was awoken by the huge shake.

She tweeted: Thought I was hallucinating during a 6.6 earthquake in Japan I have never felt anything like this in my life – laying in bed watching CNN about it.

The earthquake coincided with the pending arrival of Tropical Storm Etau in the same area with at least 13 people having died in recent flooding and landslides west of the capital.

It took place two days after a magnitude 6.9 earthquake occurred south of Tokyo, resulting in swaying buildings and tremors in the capital.
