While her ex-boyfriend
Kasey Kahl deals with the aftermath of his
drunk-and-disorderly arrest --
Vienna Girardi hung out in a bikini with her other ex-boyfriend
Jake Pavelka Lee Smith in Miami on Tuesday.
In case you forgot -- Vienna stormed off "Relationship Rehab" last month, where she was hammering out issues with Kahl. Vienna was pissed because producers blindsided her with a surprise sit-down with Lee, an ex at the time.
But now, sources close to the couple tell us Vienna and Lee have since been talking and working on their relationship.
Fun fact: Lee was also the guy that allegedly
sent Vienna flirty emails back when she was engaged to "Bachelor" Jake Pavelka.

Former "
Bachelorette" star
Kasey Kahl is adamant ... the couple he brawled with inside a Fresno nightclub are just a couple of "
Jersey Shore" wannabes bent on attaining their 15 minutes of fame.
Kahl's rep has released a NEW statement in the wake of an
explosive police report, in which an allegedly intoxicated Kahl is accused of beating up a 25-year-old named
Richard Chaney ... and smashing the dude's GF in the face at a Fresno nightclub this weekend.
Team Kahl says ... "As Kasey is in the public eye, it is not unlikely that we would not be surprised if these persons bent on attaining their 15 minutes of fame, while intoxicated and perhaps fueled by jealousy, will antagonize and attack stars such as Kasey in a 'Jersey Shore' type brawl given the opportunity."
He adds, "These persons wanted their 15 minutes, which they received, and now those 15 minutes are over."

Kasey Kahl was arrested Sunday morning in Fresno, CA -- hometown of Kevin Federline -- after cops say he was drunk and disorderly at a nightclub ... TMZ has learned.
Law enforcement sources tell TMZ ... Kahl -- who recently appeared on "
Bachelor Pad" -- was allegedly involved in an incident at a place called Club Habanos. So far, it's unclear exactly what Kahl is accused of doing wrong.
Kahl was booked at a nearby police station -- where he took one of the prettiest mug shots we've ever seen and was released a few hours later.
Kahl just finished taping the inaugural season of VH1's upcoming "
Relationship Rehab" with former GF
Vienna Girardi.
4:25 PM PST: A rep for Kahl tells us, "Kasey and his friends were hanging out outside of the club where police officers allegedly thought they were being too loud. Kasey, along with a couple friends, were taken to the police station, but were released a couple hours later. No charges were or have been filed against him."
The rep adds, "Kasey was extremely respectful and very cooperative with the police officers despite the situation, even having a good laugh because of his model-esque mugshot. The police officers noted that it was the prettiest mugshot they've ever seen come into their station."
