In this week's A-List Insider: Kylie Jenner and Tyga go public on her 18th birthday, Nicki Minaj and Meek Mill might be having a baby and Briana Jungwirth shows off her One Direction baby bump.

Kylie Jenner turns 18

Kylie Jenner used her 18th birthday celebrations as the perfect opportunity to finally go public with her rumoured rapper boyfriend Tyga. After the hip hop star gave her a Ferrari sports car as a birthday present, in front of her friends and family outside the Bootsy Bellows nightclub in Los Angeles, she could not hold back her excitement.

In footage posted on Instagram, Kim Kardashian's little sister can be seen holding her face in her hands and then hugging the Rack City hitmaker after he hands her the keys to her new Ferrari 458 Italia. Just so you know, the car is said to be priced at a whopping $320,000 (£204,000). Just throwing that out there.

You may recall there has been lots of backlash about their romance because of the eight-year age gap. Now they are official, we have a sneaky suspicion that we may soon hear wedding bells.

Nicki Minaj pregnant with Meek Mill's baby?

Nicki Minaj has sparked speculation that she is pregnant with Meek Mill's baby after referring to her boyfriend as her "baby father" during a recent concert. The Young Money star sent the rumour mill into overdrive after introducing Meek, to the stage at her Pinkprint Tour concert in Burgettstown telling the crowd: "Make some noise for my baby father."

To add fuel to the pregnancy flames, she later retweeted a congratulatory message from a fan and posted a snap of her holding her stomach and smiling happily with her beau. So it looks like Meek Mill might want to start work on learning how to change nappies and forget about his beef with Drake.
