Naaw - it's like the episode of Friends that never happened finally happened! OK, there was The One With The Stripper, but I don't recall there actually being scenes from Monica's hen party... 

Anyway, Jennifer Aniston is said to have hosted the party for her best pal / former Friends co-star - who is set to marry Snow Patroller rocker Johnny McDaid - in Beverly Hills, inviting 11 of her closest and friends, including Johnny's mum Pauline. Just put yourself in Pauline's shoes for a minute... mental.

A source revealed: "Jen went all out and had decorated the dining table with green and white bouquets, hand-made mint chocolate truffles and green velvet cupcakes, green and white napkins with shamrock place settings and Celtic charm champagne glasses." Presumably  there were also shots of Jager and VIP passes to Coppers.

Guests are said to have enjoyed themed treats such as Guinness chocolate cheesecake at the bash at California's Il Pastaio restaurant and Johnny even stopped by to make sure his wife-to-be was kicking up her heels good 'n proper.

The source added to The Sun: "Johnny even made an appearance at the end of the meal." Aaaaand that's all the details yer getting on that. 

The couple - who were introduced by Ed Sheeran - sparked rumours they'd already tied the knot earlier this year when 38-year-old Johnny appeared to be wearing a wedding band on his ring finger during a romantic stroll with 50-year-old Courteney.

Meanwhile, Jennifer - who has been engaged to her Wanderlust co-star Justin Theroux since August 2012 - hinted previously that she thought Courteney should enjoy her engagement and not rush into marrying. Not that she listened, or anything.

She said: "There is something to enjoying the engagement period I have to say, whether it's three months, one year, two, three, four, five years, who knows, enjoy it. There's no rush."
