Hookups, Breakups & Babies - July 18, 2011

- Joe Jonas has romanced some of the hottest young stars around -- Taylor Swift, Demi Lovato, and Ashley Greene, for starters -- and it seems as though he's decided to switch to models! The JoBro was seen canoodling with Karlie Kloss recently, a gal who's walked every major runway you can think of at the age of 18. Sources say they looked quite smitten at a polo match recently, and even posed in a photo booth together!

- AnnaLynne McCord seems to have moved on from her last beau, hunky Twilight star Kellan Lutz, with a new, older man. The 90210 star was seen cuddling with her 41-year-oldOfficer Down co-star Dominic Purcell! Now, there's photographic evidence of the two getting all lovey-dovey, but we have to wonder if this is a real relationship, or they're just drumming up publicity for the new flick. Hmm.



Breakups:
- We hardly believe in love after Jennifer Lopez and Marc Anthony announced Friday that they're ending their 7-year marriage. The couple, who have 3-year-old twins, issued a statement that read: "We have decided to end our marriage. This was a very difficult decision. We have come to amicable conclusions on all matters.”

Today rumors surfaced that J.Lo was having an affair with the "Cuban Brad Pitt," William Levy, who starred in her steamy"I'm Into You" music video. His rep insists theirrelationship is strictly professional.

Meanwhile, the exes apparently still plan to continue filming their new reality show, ¡Q’viva! The Chosen. The show will be an international TV talent show that will take the former couple to 21 countries in Latin America. What fun!

Babies:
- The Trump empire expanded Sunday with the birth ofIvanka Trump and Jared Kushner's "beautiful and healthy little baby." The Donald spilled the beans about his granddaughter's name Monday: Arabella Rose! We'd be hard-pressed to think of a more perfect princess name.

- We imagine Selma Blair is very ready to become a mom at this point -- she's already 11 days past her due date! The actress was spotted out and about this weekend lookingvery, very pregnant. Her projected due date was July 4, so she's bound to become a mom any day (or second!) now.

- David and Victoria Beckham just released the firstpictures of their darling baby daughter Harper Seven! Each posted a pic on their Twitter page over the weekend, just a week after her birth. In other adorable Beckham family news: The soccer also showed off like a proud dad Saturday in cleats with all 4 kids' names stitched on them!
