Kendra Wilkinson has brushed off rumours of a rift with Hank Baskett

The former Playboy model - who has four-year-old son Hank Jr. and one-month-old daughter Alijah with Hank - looked stoic as she arrived at the bash, according to gossip website RadarOnline.com.

But the 29-year-old beauty hinted on Twitter that her marriage is fine, tweeting: "Fun day with both of my Hanks #lovingsummer (sic)"

An eyewitness previously claimed that former NFL star Hank, 31, checked in a motel on Friday evening after speeding away from their mansion in his white Jeep.

The source said: "Hank was wearing a royal blue NBA shirt and long khaki shorts. He got out of the Jeep with a woman who appeared to possibly be one of the couples' baby nurses because she was wearing a medical type uniform.

"They went into the office of the motel and then pulled the jeep around to the other side where their room was located. Hank appeared disoriented and downtrodden. At one point, he kicked the ground."

Hank spent most of Friday with his father at a Major League Gaming Competition in Anaheim, California, but his wife hasn't spoken to her family since October.

Her mother Patti Wilkinson recently claimed fame had ruined her daughter.
