Celebrity PDA

Robert Pattinson and Kristen Stewart held hands when they stepped out with a group of friends in LA Wednesday. The couple kept a low profile in sunglasses as they smiled and walked around the Los Feliz neighborhood. An eyewitness tells us the couple looked "really happy and lovey-dovey" as they stopped for sushi with the group. "Kristen grabbed his arm, and they were walking and joking. She took some pictures of the friends they were with on her phone," the source says. "They seemed really together. Really relaxed."

Rob and Kristen have been spending a lot of time together ever since Rob returned from Australia after wrapping up filming for The Rover in mid-March. The two reunited for several outings over the past couple of weeks, including a stop at a convenience store and a night out with friends at a karaoke joint.

Despite spending so much time together, Kristen walked the red carpet solo at the Kids' Choice Awards in LA on March 23, but she did get a chance to catch up with her and Rob's mutual friend Katy Perry at the award show. She'll have plenty of time to spend with friends next week when she celebrates her 23rd birthday on Tuesday, April 9.

Jon Hamm and his girlfriend, Jennifer Westfeldt, showed PDA while walking their dog in LA yesterday. The longtime couple held hands while keeping their pup close. Jon is squeezing in low-key time with his leading lady in the middle of a busy work schedule. He was recently featured in Rolling Stone's April issue, where he responded to talk of his "impressive anatomy," among other topics. The interview was one among many of Jon's promotional undertakings in the lead-up to the much-anticipated debut of the new season of his show Mad Men — catch up on where we saw the Mad Men characters last before the show returns to AMC this Sunday, April 7.

Hayden Panettiere and her boyfriend Wladimir Klitschko showed lots of PDA while hanging out on the beach in Miami Saturday. The couple kissed in the water and cuddled up on the sand while soaking up the sun. Hayden wore a tiny bikini and was back in a two-piece for more warm weather fun on Easter Sunday. She vacationed in Florida with Wladimir and friends all weekend long, and shared snaps of her getaway on Twitter. The trip may have been extra special since rumors that Hayden and Wladimir got engaged started swirling last week. Hayden hasn't confirmed the relationship status, but she did talk about getting married and having kids with Wlad in the May 2013 issue of Glamour.

Gwen Stefani and Gavin Rossdale showed PDA during a visit to an LA park with their boys, Kingston and Zuma, on Saturday. The family's pup also joined in on the outing to the playground, where the boys chowed down on popsicles. The family fun continued yesterday during a visit to Gwen's parents' home for Easter celebrations. Gwen donned a white dress while her boys wore matching outfits for the holiday festivities. Kingston and Zuma got a head start on the Easter festivities last weekend, when they visited the Easter Bunny.

Gwen has been busy balancing her home life and work with No Doubt. The band recently announced that they would be canceling their tour in order to work on a new album, and Gwen and her bandmates are staying true to their word. She took to Twitter last week to reveal that she and the band are hard at work on the new music, sharing, "Writing, writing, writing. Back at it today."

Chace Crawford checked out the Knicks game at Madison Square Garden with a female friend on Friday night. The NY team took home the win against the Charlotte Bobcats, but it doesn't look like Chace spent much time watching the game. Instead he cuddled up to model Rachelle Goulding, and the duo smiled and laughed in their courtside seats.

Aside from stepping out at the Weinstein Company's pre-Oscars party weeks ago, Chace has been lying low since wrapping the final season of Gossip Girl last year. He did make news in February for voicing his interest in playing Christian Grey, though no actor has been confirmed for the lead role in the big-screen adaptation of Fifty Shades of Grey.

Doutzen Kroes donned a bikini to hit the beach with her husband, Sunnery James, and her son, Phyllon, yesterday in Miami. It was a love-filled family outing as Doutzen and Sunnery exchanged sweet kisses while playing with their little one on the sand. She and Phyllon accompanied Sunnery for the trip south where he deejayed at Miami's Ultra Music Festival over the weekend.

While Sunnery was busy at the festival, Doutzen and Phyllon wasted no time enjoying the nice weather. On Saturday, she sported another bikini for a playdate with pal Candice Swanepoel and her little man on the beach. Like Sunnery, Candice was in Miami for work obligations and kicked off the weekend modeling bikinis for a sexy Victoria's Secret shoot.

Hayden Panettiere and ex-boyfriend Wladimir Klitschko sparked up new romance rumors when they showed sweet PDA at a Miami Heat game in Miami yesterday. The couple first started dating in 2009, but broke up in May of 2011, citing distance issues. However, Hayden and Wladimir were spotted hanging out in February, raising new reports that they were dating again. Their courtside cuddle and kiss at last night's game will undoubtedly make some fans believe that Hayden and Wladimir are back together.

New romance aside, Hayden has been keeping busy over the past few weeks. She attended PaleyFest with her castmates from Nashville, and she tweeted last week that she is filming a new Neutrogena ad.
