Looks like their relationship is just revving along! Days after celebrating their fourth anniversary in Las Vegas, Pink
and Carey Hart
took their motorcycles out in Los Angeles. Their destination? Lunch at the Sagebrush Cantina in Calabasas, Calif., with friends. "After they got on their separate bikes, Pink noticed that one of her tires needed air," an eyewitness says, adding that Hart helped her to a nearby gas station and then filled up her tires. "Before getting on the
bikes again, the couple shared some loving smooches," the eyewitness says. "They looked very in love and happy."
recruited sister Kourtney
and her 3-week-old nephew Mason for a house-hunting trip in L.A. over the weekend. "Mason...slept in Kourtney's arms during the outing," an onlooker tells us. The new mom also kissed her son on the forehead while the reality stars scouted out property – including a Tuscan villa – in Beverly Hills.
kept kissing her boyfriend Scott Speer
while grocery shopping together at Trader Joe's in Toluca Lake, Calif. The duo held hands too, acting "in love and goofy," an eyewitness says. "They didn't care that people were staring at them." And Speer made his girlfriend laugh so hard, she had tears in her eyes at one point. Tisdale even jumped up on the shopping cart on the way out to the car while her beau pushed her.
waltzed into Hugo's in West Hollywood solo – but he wasn't alone for long. After sitting for a few minutes – he ordered a cup of tea and a plate of veggies while pouring over a script – the actor was joined by his model girlfriend Miranda Kerr
, who arrived in her gym clothes and gave Bloom a kiss on the lips. Nearby, Joel
and Benji Madden
were eating – they shared pancakes for a bit – though Joel later greeted the British actor with a fist bump. Also there: Sarah Silverman
and Jason Batemen
celebrating the engagement of good friend (and former NBC executive) Ben Silverman
at Philippe West Hollywood. The American Idol
host arrived by himself while Jason was on the arm of his wife, Amanda. "They all had a great time," says an onlooker.
