I had soooooo much fun celebrating Summer Solstice today with my friends at Solstice Sunglass Boutique!

It was a scorching hot day (to say the least!), but a perfect time to launch the newest line of Carrera sunglasses with a fabulous pop-up in NYC’s Meatpacking District. DJ Mia Moretti spun tunes while celebs and VIPs browsed the new collection.

Also in attendance were Adrien Grenier, Chrissy Tiegen, Victoria’s Secret Angel Erin Heatherton, and Beyonce‘s lil sis Solange Knowles.

Big names came out on Wednesday night to celebrate the launch of a brand new Cognac!

Jay-Z, Pharrell Williams and Beyonce‘s lil sis Solange Knowles were among celeb guests at the launch party for a new Bacardi-produced product, D’USSE Cognac, at The Top Of The Standard on Wednesday night (May 9).

“Hova” had a private roped off section, flanked by security, with a big flat screen TV that he insisted be installed at the event so he and his friends could watch the New York Knicks game. Rumors were swirling that wife Beyonce and close pal Kanye West would be joining the rap mogul — but they were no shows.

Party guests, which also included Adrienne Bailon (wearing Lanvin), Angie Martinez and more, took photos in the Instagram photo booth and sipped specialty cocktails while dancing the night away to the high energy tunes of DJ Jus Ske.

All in one of those New York nights!

Heidi Klum isn’t letting a divorce get her down.

In fact, she’s a “powerhouse,” according to Katharina Harf, the Chief Inspiration Officer of DKMS, the world’s largest marrow donor center.

Klum was honored at the 6th Annual DKMS Gala at the Cipriani Wall Street in New York City last night for her efforts to raise awareness for the fight against blood cancer.

Harf shared that Klum’s energy and heart is what made her a prime candidate for the “Fight Against Blood Cancer Award.”  ”She’s just an incredible woman.  I have never seen anyone like that – with that much energy.  She does it all!” Katharina told MicahJesse.com, bringing up Heidi’s four children and her very busy schedule.  ”But really the thing that strikes me is that she has a beautiful heart.”

Long-time board member Alejandro Santo Domingo, Senior Managing Director, Quadrant Capital Advisors, was also honored at the DKMS Gala for supporting organizations and charities dedicated to the cause.

Santo Domingo’s model-girlfriend Julie Henderson attended the event with him.  ”[Alejandro] inspired me to be aware of blood cancer and everything that it does to people,” she said, recalling that blood cancer is the second leading cause of death behind lung cancer.  ”I’m very proud of him.  I couldn’t be more ecstatic about [him being honored].”

The cause hit home for many people at the gala, like hip hop artist Nelly, whose life has been affected by cancer.  ”I lost my sister to cancer in ‘05, so I do a lot of awareness as far as getting people signed up on bone marrow stem-cell registries.  So anytime you could show up and show your love, it’s a beautiful thing.”

Stars like Dakota Fanning, Solange Knowles, and Ashanti also showed their support for the cause.

Rihanna and actress Eva Mendes share a laugh at the 5th Annual DKMS Gala at NYC’s Cipriani on Wall Street on Thursday night (April 28).

Also there to support: Pharrell (who played host), Gossip Girl actress Leighton Meester who came with (and wore) Vera Wang, Iman & David Bowie, Solange Knowles and Cyndi Lauper.

Before an energetic performance from Mary J. Blige, the COO of DKMS Americas, Katharina Harf, presented an award to Rihanna in recognition for her tireless work in the fight against leukemia.

“Anyone can be affected by leukemia,” said Rihanna. ““It is the number one disease children in the U.S. die of and we can change that. I encourage people to become bone marrow donors with DKMS. If we have more donors, we can save more lives.”

The Barbados-born singer went on, “I would like to dedicate this award to Shannon Tavarez who fought so bravely against this disease but was tragically taken from us far too soon.  Shannon was a great inspiration who selflessly promoted awareness of the need for donors, so that others may receive the help they need, and she will be missed.”

Great news! The event raised a record 2.5 million dollars which will help register nearly 40,000 bone marrow donors and work to save lives worldwide.
