In this week's A-list Insider: Brangelina call it quits, Mary Berry leaves Bake Off and Alexis Arquette's cause of death is revealed.

Angelina Jolie files for divorce

Just in case you've been living under a rock for the last week, let me be the person to break the bad news to you: Brangelina is no more. Hollywood A-listers Brad Pitt and Angelina Jolie are getting a divorce and if social media is anything to go by, fans are heartbroken, celebrities are shocked and Jennifer Aniston is somewhere celebrating.

Ang filed documents citing irreconcilable differences and is seeking physical custody of the couple's six children. Her lawyers claim the split was 'for the health of the family' but Brad released a statement saying he is 'saddened' by her decision to end their marriage after just two years.

The couple, who have been together for together for since 2014, have been dogged with rumours of split for months and now the question on everyone lips is 'what went wrong?'. There have been reports of infidelity, conflicting parent styles and even a strained working relationship. All speculation but I've got a feeling this divorce may get messy.

Fans of Great British Back Off were dealt another blow on Thursday morning when Mary Berry quit as judge, ahead of the show's move to Channel 4.
