There was a spike in celebrities carrying carrying cross body bags yesterday (at least three were seen) and the weird thing was they were all spotted in countries that are not their own.

If you can’t take a trip abroad this summer, indulge me for a minute and hop on with me and these celebs to take a short trip ’round the world via this post. Find out who was spotted where, starting with Katrina Bowden:

American actress Katrina Bowden was seen out in Sydney with her boyfriend yesterday afternoon. The cute couple was spotted walking in the city holding hands and Katrina was looking very stylish in an all-black clothes and sandal booties. The “30 rock” star is currently in Australia to shoot the Spring campaign for the Australian fashion label Wish.

Kylie Minogue breezed right into the Radio 2 studios in London looking fresh as a daisy in a crisp white shirt, khaki harem pants and beige accessories. She punched up her mostly neutral-colored outfit with a gold Chanel mini purse.

Sienna Miller and Emma Watson, arguably two of the world’s most popular British actresses right now, attended the Glastonbury Music Festival at Worthy Farm in Somerset, England last Saturday June 26.

Both of them donned comfortable cut off denim shorts but that’s where the similarities ended. Sienna and Emma’s Glastonbury styles couldn’t have been more different than night and day.

Here’s what Emma Watson wore – a white sleeveless button down shirt, high-waisted denim shorts held by a leopard-printed belt, a Louis Vuitton bag and plain tennis shoes:

And here’s what Sienna Miller wore – just a loose grey tank top, denim shorts and combat boots, but piled on with accessories like a panama hat, a crochet vest, a red patterned sling bag and various pieces of jewelry:

Emma Watson was cool and casual in her very basic, very simple getup. Sienna Miller on the other hand displayed her honed boho chic sense of style by incorporating interesting pieces into her outfit.

Whose Glastonbury style do you prefer better – Emma Watson’s or Sienna Miller’s?

If your answer is Emma Watson, check out some of these cross body purses that are similar to Emma’s LV bag in the picture above:

1. Rioni Heritage Soho Messenger Bag, $116.80; 2. Etienne Aigner Logo-Patterned Cross Body Bag, $35.43; 3. Adi Designs -M- Collection European Linen Bag, $72.28.

If your answer if Sienna Miller, here are some fabric sling bags that can go from the grocery store, to the beach or to a music festival like Glastonbury:

1. San Juan Gypsy Bag (Guatamela), $37.39; 2. Cotton Knit Cinnamon Sling Bag (Nepal), $36.74; 3. Hmong Tradition Cotton Sling Tote Bag (Thailand), $34.76; 4. Cotton Hieroglyphs” Handbag (Thailand), $31.49.

Funny how their American counterparts also prefer to use cross body bags for music festivals. Read more about the bags that Dita Von Teese, Katy Perry and the Hilton sisters used at the Coachella Music Festival last April 2010.

Well wouldn’t you know it. KAVU Bags, a brand which we’ve featured time and again here on Cross Body Purses, is the best-selling messenger bag brand on Zappos.com.

Aside from being reasonably priced, customers who have bought bags from KAVU love that they’re functional, have a lot of compartments, and are just the right size (enough room to carry essentials without becoming bulky and heavy). I’d also like to add “come in nice prints and colors” to that list – KAVU bags come in practically every color of the rainbow and their basic designs allow their bags to become unisex depending on what color you choose.

So without further ado, here is KAVU’s and Zappos.com‘s best-selling messenger bag, the Keeper and it’s new perfect-for-the-summer colors:

The KAVU Keeper‘s new colors (clockwise from top left): Sunset Petals, Blue Floral, Mauve Floral, Dawn Petals and Pink Majestic

These new bright and summery colors are $36.00 each. For those who want simpler designs, the KAVU Keeper is also available in plain colors such as black, khaki and natural. The plain ones go for $41.00 a piece.

What’s your everyday go-to bag for this summer?
