In this week's A-List Insider:

Lady Gaga gets engaged, Amber Rose comes for Kim Kardashian and Jacqueline Jossa becomes a mum.

Lady Gaga gets engaged

Lady Gaga had an extra special Valentine's Day this year because her boyfriend Taylor Kinney decided to put a ring on it.

After The Vampire Diaries actor popped the question with heart-shaped diamond engagement ring on the most romantic day of the year, The Bad Romance singer confirmed the engagement on her Instagram account, telling fans: "He gave me his heart on Valentine's Day, and I said YES!"

The future Mr and Mrs Kinney celebrated their impending nuptials at Gaga's family restaurant in Manhattan.

Lady Gaga and her soon-to-be husband met on the set of her 2011 music video You and I, when he played the man of her dreams. They started dating a few months later, broke up in May 2012, but true love prevailed and they got back together a month later.

Amber Rose at war with the Kardashians

And over in reality TV, Amber Rose is at war with the Kardashian-Jenner sisters.

It all kicked off on social media after Rose blasted Kylie Jenner during an interview with K Foxx on Power 105.1's The Breakfast Club, insisting she is a baby that "needs to go to bed at seven o'clock'. She added that the 17-year-old's rumoured boyfriend Tyga, 25, should be "ashamed".

In response to Amber's comments Khloe took to Twitter in her little sister's defence, and all hell broke loose.

During the mud-slinging, Khloe quoted Amber who once told Fox news she has been a stripper since she was 15 and Amber called Kim a whore.

What makes this drama even more awkward is the fact that Amber is Kanye West's ex-girlfriend.

Jacqueline Jossa becomes a mum

And finally Eastenders star Jacqueline Jossa has welcomed her first child with her boyfriend Towie star Dan Osborne.

The 22-year-old actress, who plays Lauren Branning on the BBC soap, gave birth to a baby girl called Ella over the weekend.

"Baby ella osborne was born yesterday thankyou @DannyO and @Sarabro2 for everything. Amazing. She's perfect," she wrote.

The new parents were all smiles when they brought their daughter home from the hospital. Although Jacqueline is new to motherhood Dan, has had plenty of practice with his one-year-old son Teddy from a previous relationship.
