Beyoncé and Jay-Z may have taken their controversial trip to Cuba more than a month ago, but she recently released new — and totally adorable — images of their anniversary getaway on Tumblr. Beyoncé and Jay-Z cuddled up in a few of the snaps, while Beyoncé went solo in others.

Since they wrapped up their getaway in April, it's been all about business for Beyoncé. Her bikini ads for H&M were released, she kicked off her Mrs. Carter Show world tour, promoted her voice role in Epic, and walked the red carpet at the Met Gala. While the tour continues, Beyoncé is now facing pregnancy rumors after she canceled a performance in Belgium earlier this week. She returned to the stage on Wednesday and is expected to perform in Zurich tonight. Regardless of the speculation about baby number two, one thing is for sure — these pics of her and Jay-Z are too cute, so click through to see them all!

Tiger Woods and his girlfriend, Lindsey Vonn, kicked off the week with a relaxing afternoon on the water in Palm Beach. On Tuesday, the duo went boating on Tiger's yacht, Solitude, with his kids, Charlie and Sam. Tiger lounged shirtless while he fished off the side of the vessel, and Lindsey was spotted snapping pictures from the dock in her bikini. The couple are back to Tiger's home base in Florida after traveling to NYC to attend the Met Gala earlier this month. Tiger will be on the go again soon, though, since he's set to host his annual Tiger Jam charity poker tournament in Las Vegas this Friday and Saturday.

Tiger and Lindsey have been going strong since revealing their relationship in March and have showed mutual support for each other publicly. Lindsey's had Tiger by her side as she recovers from the knee injury she sustained during the skiing world championships in Austria in February, and she cheered him on during the Masters last month.

Nina Dobrev and Ian Somerhalder were both in attendance at today's CW upfronts presentation in NYC. Nina and Ian walked the red carpet separately but during the event they shared the same stage even after news of their split was announced earlier this month. They were together for three years, though they became one of the many TV costar couples that couldn't make it work off screen when they called it quits.

Nina and Ian are in the Big Apple on behalf of The Vampire Diaries, which will air its season finale tonight — make sure to tune in for our LIVE Vampire Diaries viewing party tonight at 4:30 p.m. PDT/7:30 p.m. EDT.

David Beckham had a smile on his face as he left the Paris Saint-Germain training facilities in Paris today. It was one of the last times he'll be visiting the field since earlier today he announced his plans to retire at the end of the season. David's been in the soccer spotlight since he was 14, and he'll wrap up his successful career in his final game with PSG later this month. We'll certainly miss seeing David on the field, especially since he had a hot habit of going shirtless. Hopefully this weekend's match will provide one last glimpse at his abs — and a whole lot of cuteness in the stands from his adoring family.

The honeymoon continued for Keira Knightley and her new husband, James Righton, in Corsica today. Keira wore a bikini for a dip in the ocean, though she's showed off other looks with her laid-back honeymoon style, which has even included wearing the same dress three different ways! For her dressed-down swim, she was joined by shirtless James, who showered her with kisses in the water. They've been all about the sweet PDA during their romantic getaway and showed similar affection while enjoying lunch and strolling the beach last week.

Keira and James jetted off to France after tying the knot on May 4. They were wed at the town hall in Mazan and celebrated after the ceremony with friends and family at a reception held at her parents' farmhouse.

It was an extraspecial weekend for Anna Paquin and her family since it was her first time celebrating Mother's Day! They got a head start on the fun on Saturday, when they met up with friends for a party at a Malibu park. Anna and her husband, Stephen Moyer, took turns holding onto their boy and girl twins, whose names have not been revealed, and mingling with guests. The babies were born in September and since then have joined their parents for shopping trips and strolls along Venice Beach, though their sweet faces have been kept mostly under wraps. It hasn't been all about parenthood for Anna and Stephen, though, since they've also been working on the sixth season of True Blood. The series doesn't return until June 16, but you can check out pictures from True Blood season six now to gear up for the next installment!
