Serena Williams headed to Hyde Lounge in Hollywood with pal Brittny Gastineau on Monday night ... and looked like she needed to "hyde" her head!

Williams kept her head down, which showed off her bald spot on top. We love you, Serena, but that needs to get taken care of!

Other than the hair affair, the tennis star looked sexy in a see-through top and leather jacket.

This isn't the first time we've seen celebs out with embarrassing (or should we say emHAIRassing?) bald spots! See who else is a member of The Bald And Not-So-Beautiful club after the jump!

This may be a new couple alert, but it's also a bit of an odd couple alert!

We haven't seen Serena Williams on the dating scene since she split from rapper Common in 2010, but last night the tennis superstar went out with country
singer Jake Owen! The duo dined to Matsuhisa in Beverly Hills, and they seemed just as surprised as we were when they left the sushi restaurant. Serena tweeted, "@jakeowen had so much fun tonite! Yea can't wait to see concert tomm! Fun time see u tomm/today!!!"

A photographer on the scene tells X17online exclusively that Serena and Jake didn't make much of an effort to sneak out separately, but they tried to keep their exit "as low key as possible." Hmm, so are they just friends or something more?

Tennis star Serena Williams gave us a "Haaeeyy" with her arms in the air at the beach yesterday in Miami.

This is a girl who's not afraid to show off her bod, and rightfully so -- she works hard on the court. THIS isn't a woman Nicole Richie, Scarlett Johansson worried about rumors and gossip concerning her body. She loves herself and it shows. Yay for Serena!

Spotted: Tennis ace Serena Williams soaking up the sun on the beach in Miami with a few close pals. After her recent hospitalization for a blood clot in her lungs, we're happy to see Ms. Williams is relaxing -- and clearly feeling better!

Tennis superstar Serena Williams' new Wii, PlayStation 3 and Xbox 360 game Top Spin 4 is going to be released this spring, but this 57 second ad won't be appearing on TV any time soon...

Williams and actress Rileah Vanderbilt pretend to battle it out on the tennis court as clips from the game play in the background, but after listening to the grunts and getting an eyeful of their sexy workout wear, it's easy to see why parent company 2K Sports isn't planning on using this as an official ad. "As part of the process for creating marketing campaigns to support our titles, we pursue a variety of creative avenues," 2K Sports said in a statement. "This video is not part of the title's final marketing campaign and its distribution was unauthorized."

Vanderbilt uploaded this video on YouTube earlier this week and Williams told her fans to "Stay tuned for a awesomely sexy video I am tweeting later," but it seems as though that's when 2k Sports pulled the plug on the ad, because no one has mentioned it since then!

Serena Williams was rushed to Cedars-Sinai Medical Center in Los Angeles on Monday for a blood clot in her lungs, according to People.

Williams' rep said her client suffered a pulmonary embolism last week, and she was hospitalized for "a hematoma suffered as a result of treatment for a more critical situation." Her rep added, "Doctors are continuing to monitor her situation closely to avoid additional complications."

Last night the 29-year-old tennis star tweeted, "Tough day..." and she also responded to BFF Kim Kardashian's excitement over her new music video, so it sounds like she's on the road to recovery.

After last night's Teen Choice Awards, Kim Kardashian and BFF Serena Williams re-fueled at Il Sole on Sunset where Kim was mobbed by fans!

The recent Wimbledon champ, Serena, was largely ignored while Kim graciously stopped to pose for pix and sign autographs, handling it all with grace and style.

Speaking of being gracious, it seems like Kim has decided to forgive Kourtney's baby-daddy Scott for his recent violent outburst in Miami.

“I have seen a big change in Scott and I have actually seen him make a transition, so it’s actually easy for me to accept him now that I actually see a difference in him,” Kim told OK!

Kim recently announced that she and her sisters were launching another clothing line together.

Looking gorgeous in a white Eres one piece, tennis great Serena Williams is getting loud and proud in the August issue of Harper's Bazaar.

When it comes to comparing her voluptuous body to sister Venus', Serena tells the mag:

"I was 23 when I realized that I wasn't Venus. She's totally different. I'm super curvy. I have big boobs and this massive butt. She's tall and she's like a model and she fits everything. I was growing up, wanting to be her, wanting to look like her, and I was always fitting in her clothes, but then one day I couldn't. But it's fine. Now I'm obviously good, but it's a weird thing. . . . To this day, I don't love my arms. People want more fit arms, but my arms are too fit. But I'm not complaining. They pay my bills."

You go, girl. Embrace those curves!
