Last episode of The Real Housewives of Beverly Hills promised a lot of entertainment for viewers. The ladies surprised Lisa Vanderpump's birthday as her restaurant called PUMP when Vanderpump's husband insisted that they had to make a fake emergency stop at the restaurant.

Viewers of the show were interested to see Brandi Glanville there, who hasn't been on the best terms with Vanderpump.

Vanderpump and Glanville have had problems in the past season, especially when Vanderpump started telling various sources of her and Glanville's past friendship. This season the two have now been seen as "frenemies."

Glanville was thrilled to receive a party invitation from Vanderpump's husband, Todd. However, Todd warned Glanville to be on her best behavior. That meant keeping the swearing to minimum, little alcohol consumption, and no bullying of any kind.

Luckily for Glanville the warning was not much of a challenge since she started a 21-day cleanse of no sugar or alcohol earlier this season. She was inspired by another one of the show's stars, Yolanda Foster, who likes to complete her diet with a variety of pills.

At the party, Glanville had to earn Vanderpump's approval by singing to all the guests. Vanderpump knew how much Glanville disliked singing, but she wanted to know just how far Glanville would go in order to pass her inspection.

Apparently, Glanville did a fine job along with the other ladies at the party. Vanderpump was thrilled to share her special day with people her are sweet and supportive, even Glanville.
