We all know about Ben and Matt, and Nicole and Naomi being long-term besties, but did you know that these celebs are best friends too? Jessica Alba & Jessica Simpson A strange twosome this, what with Alba being one of Hollywood\'s most controlled, uptight stars and Jessica more of a let-it-all-hang-out gal, but the two have bonded over the years - with Alba attending Jessica\'s recent baby shower - and plan to spend plenty of mummy time together when Jess\'s baby arrives. \"New goal: look like @jessicaalba after baby. Job well done lady!\" Jessica recently tweeted about Alba\'s post-Haven bod. Causing 30-year-old Alba to respond, \"OMG! Ur so sweet! Thx hon!\" Kate Hudson & Liv Tyler The Hollywood and rock royalty have been best pals for years and co-starred in 2000 flick, Dr T And The Women. And living near each other in New York, Liv has revealed that the besties always get ready together for a big night out, spilling, \"We have a little ritual where we meet at 2pm or 3pm, and we drink champagne and we do hair and make-up. We take pictures and gossip, and have a great time.\" Heidi Klum & Sandra Bullock The German supermodel and America\'s sweetheart have been friends for a while now, and recently bonded further over their very public divorce experiences, sharing a wild girls\' night out at Hollywood eatery, Mr Chow. \"They were in there for hours,\" spilled a diner. Adding of their post-dinner drinks, \"The girls had two shots of tequila each - and they high-fived both times!\" Julia Roberts & Natalie Portman Julia and Natalie struck up a very tight friendship on the 2004 set of Closer, with Julia taking on the protective role of the 14-years-her-junior actress, and Natalie famously giving Julia a gold necklace with the word **** on it as a joke post-filming gift. And Julia has championed her pal ever since, writing a piece in industry bible, Variety, in support of Natalie\'s Oscar nomination for Black Swan, gushing, \"She is always lovely, always watchable, always interesting. I, as many, first fell deeply in love with Natalie in Luc Besson\'s film The Professional. A performance like the one she delivers in Black Swan affirms that my professional admiration for her was well placed. Now as the years have kindly made her a li\'l friend (that\'s a joke for Natalie), I am simply beaming with pride for her.\" Jennifer Lawrence & Zoe Kravitz This gorgeous pair met on the set of X-Men: First Class, further bonding when Zoe\'s dad, Lenny, won the role of Cinna opposite Jennifer\'s Katniss in The Hunger Games. And Zoe remembers their first proper hanging out session as being pretty unorthodox. \"I\'d met her a few times, and she was like, ‘You should come over and we\'ll hang out\',\" spilled 23-year-old Zoe. \"So, I go over to her apartment, and she opens the door in a towel. She\'s like, ‘Come in, sorry, you\'re early, I was about to shower.\' And she drops her towel and gets in the shower, and starts shaving her legs, totally naked. She was like, ‘Are we here yet? Is this OK?\' And I was like, ‘I guess we\'re there!\'\" Zac Efron & Ashley Tisdale Having managed to stay friends with both her HSM co-stars, Zac and Vanessa in the wake of their split, Ashley calls Efron her \"brother and best friend\", with the pair usually to be spotted packing on the friends-style PDAs in LA. Having been pals for six years, Ashley insists there\'s no romance between them, tweeting of her recent 26th birthday party, \"So happy Zacary made it to my party! He\'s my brother/best friend.\" Salma Hayek & Demi Moore Inviting long-time best pal, Demi, to Paris to shop to take her mind off her divorce drama, Salma calls the 49-year-old actress \"an inspiration\", revealing that she wishes she had Demi\'s \"discipline\". \"I like to eat,\" admits Salma. \"I\'m always on the edge of how much can I eat without looking too... you know. And exercise is not my thing, though I do it. [I\'m] not like Demi. She\'s so disciplined; I wish I could be like that. You watch: Demi will be back. She\'s an inspiration to all women.\" Kate Winslet & Reese Witherspoon The Oscar-winning pair bonded back in 2007, after Kate moved to Reese\'s exclusive LA enclave when she was still with ex-husband, Sam Mendes. \"Imagine my good fortune when Kate Winslet moved into my neighbourhood and rang my doorbell,\" spilled Reese of first meeting the English actress. \"And said, ‘Dahling, Sam is off shooting, and I believe our children are the same age. Could they possibly have a play date and oh, by the way, it\'s almost 9 o\'clock and I\'ve had nothing to drink - do you have any wine?\'\" Robert Pattinson & Katy Perry The A-list pair were friends long before R-Patz started dating his Twilight co-star, Kristen Stewart, as they shared mutual friend, Shannon Woodward (Andrew Garfield\'s actress ex) when Rob first moved to LA. And Katy has since welcomed K-Stew into her gang, with the couple recently taking part in a concert taping for Katy\'s upcoming 3D flick, Katy Perry: Part of Me. \"They are obviously very close to Katy,\" spilled an insider of a recent night out. \"When Rob and Kristen arrived she was really pleased to see them.\" Justin Timberlake & Jimmy Fallon The pop star-turned-actor and the talk show host met when Jimmy hosted the 2002 MTV Awards. \"I remember talking backstage during those VMAs. I was totally nervous and you were nervous and we both ended up having good nights,\" revealed Jimmy. \"We\'re good luck to each other, like each other\'s rabbit foots.\" Adding of approaching JT to be the first guest when his chat show launched, \"I remember asking [him], ‘Dude, would you come on the first show?\' And without even thinking [he was] like, ‘Yeah of course. No problem.\'\" From: Gulfnews
