Lauren Conrad: Happy Birthday at Hyde!

Lauren Conrad dolls up in a ‘Vista Sequin Tunic Dress’ from alice + olivia as she celebrates her birthday at Hyde Bellagio in Las Vegas on Friday night (February 10).

The 26-year-old designer/author partied it up with a group of friends which included her former Hills costar Frankie Delgado.

Frankie actually grabbed the mic near DJ Devin Lucien and asked the crowd to join him in wishing Conrad a “very happy birthday.” She also received a four-tiered pink and purple birthday cake adorned with flowers from the club!

Lauren is also pictured running a few last minute errands, wearing [BLANKNYC] skinny jeans, in Los Angeles before hoping a flight to Vegas earlier in the day.
