This
Kentucky Derby was full of highs and lows this weekend as the usual slew of celebrities donned their finest hats and preppiest suits to catch the big race. Naturally Heidi Montag and Spencer Pratt were there and looking ridiculous and even Adrian Grenier cleaned up for the big day — well, kind of. Nick Lachey, his brother Drew and Joey Fatone hosted the after party and didn't look too emotionally scarred by having to see the runner up horse Eight Belles have to be euthanized on the track immediately after breaking both her ankles finishing the race.

The sunny weather brought out folks around the country. Tom Cruise and his older kids caught a game, Keri Russell hung out with lil River and Jessica Alba celebrated her last birthday before babe. Take a look at our gallery to see who was up to what.

Nick Lachey was nice enough to lend
his LAX expertise to Drew and his family, dropping them off for a flight on Friday. He'll have to cut back on his busy life of jet-setting now that he's got a new gig all lined up. Nick's Summer plans include hosting a
High School Musical-type reality show.

The cast of
Speed Racer saw a perfect opportunity to promote their film at the 2008 Toyota Pro/Celebrity Race in Long Beach on Saturday. Emile Hirsch and Matthew Fox looked cool and casual as they watched from the sidelines, while the ladies got a bit more dressed up. Christina Ricci wasn't going to let a sports event stop her from looking girly in her high heels and cute hair —
what do you think of her wavy bob? Drew Lachey slipped into a jumpsuit to race for charity and Nick couldn't resist pulling the bunny ears for the photo op — we guess that's just what big brothers are for.

The brothers Lachey headed to LAX yesterday to get out of town for what looks like a boys-only Labor Day weekend getaway. Lately it seems like Nick spends most of his time
hanging around airports with Vanessa, but his brother is making career moves. Riding the coattails of his big
Dancing With The Stars win last year, Drew is going to try his hand at hosting a new spinoff called Dance War: Bruno vs.

Left over weekend news and a reason to laugh after the
sad real life event that is taking place today. Reality television's finest came
out to Dance to Erase MS this weekend at the Century Plaza. The stars walked the runway to raise awareness and cash for multiple-sclerosis treatment and research.
